In the last years, new rotorcraft configurations have increased the attention among industries, through which the tiltrotor one due to its capability of combining both rotorcraft and aircraft advantages. However, there are situations where the vertical take-off mode could be enhanced in hard environmental and flight conditions. Therefore, to address this challenge, this work aims to develop a methodology to characterize a roll take-off model for a general tiltrotor configuration in such situations. By combining the integration of the equation of motion and geometrical assumptions, the runway distance is determined for an acceptable range of nacelle tilting angles. The process is developed by meeting the requirements defined by the regulations, combining the aircraft certification standards (CS23 and CS25) with the available tiltrotor certification basis from the FAA project #TC3419RC-R. Following the Nominal application, a sensitivity analysis is carried out, which studies the main

Numerical simulation of Vehicle Dynamics performance of a Formula 1 Car based on 2022 regulations with integrated Power Unit

2022-01-04453/29/2022

The Formula One World Championship gathers the best of engineering to produce the safest and the fastest cars in straight lines and corners. The new FIA budget restrictions and the cost of testing push the teams to use numerical simulations for the development of their car, aiming to reproduce the behaviours of the vehicle on different racetracks. Current published models use a rigid body representation of the chassis to describe the motion of the car. This omits the influence of the powertrain, in particular by not fully representing the action of the Motor Generator Unit-Kinetic (MGUK) system acting on braking. The aim of this work is to predict the vehicle dynamics performance of a Formula One car from a powertrain perspective on three circuits of the Formula One Championship race Calendar. The vehicle model developed on GT-Suite and which complies with the FIA 2022 technical regulations, includes the main elements for predicting vehicle dynamics, such as the vehicle body, wheels

Identifying Cybersecurity Focus Areas in Connected Cars Based on United Nations Regulation No. 155 Attack Vectors and Beyond

2022-01-01413/29/2022

The arrival of 5G will enable vehicles to become better connected. In order to allow this evolution to manifest safely, the UNECE World Forum for Harmonization of Vehicle Regulations (WP.29) introduced the United Nations Regulation No. 155(UN-R155) this January, with expectations that at least 54 countries will mandate it starting July 2022. This regulation provides 69 attack vectors manufacturers are required to secure against, although it does not include specific countermeasures. Security methods and corresponding technologies change with time and are influenced by evolving connected car technologies as well as the threat landscape. Implementing effective cybersecurity means conducting a thorough risk analysis and prioritizing what needs to be achieved. Trend Micro Research conducted a risk analysis on each of the 69 attack vectors from a current and future perspective. In addition, we went beyond the attack vectors listed in UN-R155.

Modular HD Transmission Family for Fuel Consumption Reduction Tailored for Indian Market Needs.

2021-26-00499/22/2021

Global warming is the driver for the introduction of CO2 and Fuel Consumption legislation worldwide. Indian Truck manufacturers are facing the introduction of Indian Fuel Efficiency Phase 2. In the European Union the CO2 emission monitoring phase of the most relevant truck classes will be completed in June 2020 by usage of the Vehicle Energy Calculation Tool VECTO. Indian rulemaking is currently also considering an adaptation of VECTO for the usage in the India Indian truck market used always to be very cost sensitive. Introduction of Bharat Stage VI Phase I already led to a significant increase of product costs, which not directly manifest benefits to the end users. Therefore, it will be of vital importance to keep the additional product costs for achievement of future fuel consumption legislation as low as possible as long as they don’t refund them in real world operation. So far, confirmation of Indian Fuel consumption requirement fulfillment takes place under constant driving

The Increasing Importance of Particles, Volatile Organic Compounds and Ammonia in Future Air Quality Policy

2021-01-06074/6/2021

Ensuring continuing environmental and health improvements, it is important regularly to reassess what pollutants from vehicles are targeted. Are the right compounds being regulated? The Emissions Analytics’ presentation looks at a range of pollutant sources that may need to be considered to give a holistic view of the environmental impact of vehicles, supported by data from its independent, real-world EQUA test programme. Post-Euro-6 emissions regulation in Europe is an opportunity to simplify and refocus on emerging environment threats. Certain unregulated tailpipe pollutants, such as ammonia, which contributes to secondary particle formation, are candidates for future regulation. Volatile organic compounds are of interest from several angles: vehicle interior air quality and the off-gassing from materials; tailpipe speciation of hydrocarbons including formaldehyde; and off-gassing from tyres. Tyre wear emissions are currently unregulated but are believed to be a growing contributor

Development and Characterization of Aerosol Conditioning Devices for Solid Ultrafine Particle Measurement from Diesel Engines: A Review

2021-01-06154/6/2021

Emission regulations mandate the measurement of solid particles of size greater than 23 nm according to UNECE informal working group particle measurement protocol (PMP). The volatile particles from the engine exhaust are removed by heating and dilution in a device according to the UNECE PMP program. The analysis of solid particles from diesel engines requires aerosol conditioning systems, which can effectively remove volatile particles/species with minimum solid particle losses. Currently, the regulations only allow using an evaporation tube for the measurement of solid particles. Different laboratories have also demonstrated other alternatives such as thermodenuder and catalytic stripper for measuring the solid ultrafine particles emitted from the diesel engine. This paper reviews the recent literature related to the thermodenuder and catalytic striper’s design and operating characteristics. The performance parameters, such as penetration efficiency and volatile removal efficiency

Vehicle Safety Communications Landscape Clarifies with Controversial FCC Ruling

21AVEP01_061/1/2021

The vehicle-to-everything communications-technology debate is “solved” by federal regulators - and cellular vehicle-to-everything (C-V2X) appears to be the winner. After years of transportation-industry tussle over competing technologies to enable communications between vehicles and a “connected” environment, the Federal Communications Commission (FCC) has decided the matter. On Nov.18, 2020, the FCC ruled it will allow a portion of the 5.9-GHz “Safety Spectrum” long reserved for the transportation sector to be allocated to unlicensed private usage such as Wi-Fi internet connectivity. The ruling effectively eliminates the future for Wi-Fi-based Dedicated Short-Range Communications (DSRC) and locks in the advancing alternative, cellular vehicle-to-everything (C-V2X). Despite many experts' opinion that the decision to now limit transportation communications to just the upper 30 MHz of the 75-MHz spread within the 5.9-GHz (5.850-5.925 GHz) Safety Spectrum has not been sufficiently

Comparison of Particulate Matter and Number Emissions from a Floating and a Fixed Caliper Brake System of the Same Lining Formulation

2020-01-163310/5/2020

The particulate emissions of two brake systems were characterized in a dilution tunnel optimized for PM10 measurements. The larger of them employed a fixed caliper (FXC) and the smaller one a floating caliper (FLC). Both used ECE brake pads of the same lining formulation. Measured properties included gravimetric PM2.5 and PM10, Particle Number (PN) concentrations of both untreated and thermally treated (according to exhaust PN regulation) particles using Condensation Particle Counters (CPCs) having 23 and 10 nm cut-off sizes, and an Optical Particle Sizer (OPS). The brakes were tested over a section (trip-10) novel test cycle developed from the database of the Worldwide harmonized Light-Duty vehicles Test Procedure (WLTP). A series of trip-10 tests were performed starting from unconditioned pads, to characterize the evolution of emissions until their stabilization. Selected tests were also performed over a short version of the Los Angeles City Cycle. PM2.5 emissions of burnished pads

A Systems Design Approach to Fuel Measurement for Hybrid-Electric Aircraft

F-0076-2020-16428

10/5/2020

Aircraft development efforts are rapidly shifting toward the use of distributed electric propulsion. As the industry moves along a path to full electrification, hybrid propulsion systems will be increasingly employed where battery technology does not support a fully electric design. The fuel systems in new aircraft designs can be challenging, and the existing regulatory framework may not be capable of dealing with unique aircraft designs that do not neatly fit within existing categories. This presents a challenge to aircraft designers. Fuel remains essential to the propulsion system, and an optimal, yet simple fuel system will be necessary to leave room in the design trade space for more challenging and risky functions. Understanding the certification requirements and having a basic knowledge of the tradeoffs in fuel measurement accuracy are the key elements necessary to support a systems approach to optimizing a fuel measurement subsystem.

Potentials and Challenges of a Brake Particle Emission Collecting System

2020-01-163510/5/2020

Brake particle emissions as a part of non-exhaust emissions are becoming more and more relevant, various international research activities can be stated. Also from the legislation side, first hints are given in regards of possible regulations. One possible approach for the reduction of brake particle emissions deals with the collection of those particles close to the foundation brake. The presented paper will follow such an approach and give some insights. In a first step, the technical layout is described for bench and vehicle testing. While for bench testing a PMP-like style of the setup could be chosen, the vehicle test setup is oriented on conventional wheel dust measurements. Hence, presented results of laboratory testing are dealing with PN and PM measurements. Also the impact on particle size distribution is discussed. It can be stated, that the particle collecting system is able to improve PN and PM emissions. Additionally, ultra-fine particles are almost eliminated. The

On-Road Emissions of Euro 6d-TEMP Vehicles: Consequences of the Entry into Force of the RDE Regulation in Europe

2020-01-22199/15/2020

Human health and the environment are heavily impacted by air pollution. Air quality standards for Nitrogen dioxide (NO2) and particulate matter (PM) are commonly exceeded in Europe, particularly in urban areas with high density of traffic. Road transport contributed to 39% of NOx emissions, and 11% of PM emissions in the European Union (EU) in 2017. Measurements with Portable Emissions Measurement Systems (PEMS) showed that most Euro 5 and Euro 6b diesel vehicles emitted significantly more NOx on the road than their permissible limit in the laboratory type-approval test. In that context, EU Real Driving Emissions (EU-RDE) regulation aims at securing low on-road emissions of light duty vehicles under normal conditions of use. This paper assesses the tailpipe emissions performance of Euro 6d-TEMP gasoline and diesel passenger cars, type-approved after the entry into force of the RDE regulation in September 2017.

Soot Load Monitoring in Gasoline Particulate Filter Applications with RF-Sensors

2020-01-21719/15/2020

With the start of Euro 6d regulations, gasoline particulate filters (GPF) have become standard equipment in European vehicles with gasoline-direct-injection engines. GPFs will also be broadly applied to meet the upcoming China 6 regulations. An existing challenge with GPFs is accurate soot load detection to manage the pressure loss across the exhaust system and to protect the GPFs from soot overload, which could potentially cause damage as result of uncontrolled soot oxidations. Systems with the GPF located in the under-floor position have a higher potential risk of soot overload due to lower temperatures, which can result in higher soot accumulation rates. The accuracy of existing soot estimation methods such as evaluation of the pressure drop of the soot-loaded GPF or model-based balancing of soot accumulation versus soot oxidation rates are sensitive to transient operating condition of a vehicle. Identifying an alternative method for accurate monitoring of the soot-loading state of

A System and Method to Determine Soak Time

2020-01-20169/15/2020

In a competitive engineering business world, there is a constant demand to meet stringent emissions and on board diagnostic (OBD) regulations in a cost-effective manner. Engineers are tasked with the responsibility to innovate and design solutions around cost-cutting measures that involve reducing bill of material costs on the printed circuit board (PCB). Varied features in commercial application specific integrated circuits (ASIC) devices makes it more challenging to create consistent engineering design methods to provide critical inputs for controls and diagnostic strategies. In addition, continuous evolution of the emissions and OBD regulations in the different markets make it challenging for ASIC design manufacturers to evolve their hardware designs quickly. One such input is soak time. Soak time is typically defined as the amount of time the engine has been turned off. Emission controls and OBD algorithms use soak time to enable cold and hot start processing strategies. There are

New EU Patent System Could Unify and Simplify Process

20AVEP05_085/1/2020

Europe's new unitary patent system and a flurry of AV legislation could be a boon to innovators. To engineers who are developing autonomous vehicle (AV) technologies, the legal landscape around innovation can look increasingly complex. And the patent path may seem daunting. But advances to simplify the process are on the way, beginning with the introduction of a European unitary patent system that “promises to considerably simplify the current patent system,” says Stuart Latham, partner and patent attorney at Withers & Rogers, one of Europe's largest firms specializing in intellectual property. Under the new system, businesses will be able to apply for a single unitary patent spanning all EU member states that opt to introduce the new system without the need to validate the patent at jurisdictional level. Latham said this “could provide a cost-effective way to secure commercial protection across the EU, allowing time for markets and regulatory environments to continue to evolve.”

20AERP05_025/1/2020

Uncertain Regulations Stall the Implementation of Counter-UAS Technology in The U.S. In early September 2019, a radical environmentalist group called “Heathrow Pause” threatened to shut down Heathrow Airport in the UK by flying drones within the airport's no-fly zone to call attention to climate change. Some Heathrow Pause members were arrested the day before their previously announced fly-date (9/13) and on the day itself their drones were unable to take off, electronically jammed by the authorities. The protest represents a new wrinkle in the fast-moving world of unmanned aircraft systems (UAS) use and integration. As previous drone-induced airport disruptions at Heathrow and Gatwick in the UK and at Newark Airport, New Jersey in the U.S. demonstrate, society will need to prevent as well as facilitate drone use in daily life.

Simulation of Aftertreatment Thermal Management Strategies for Low-Load Operation

2020-01-03594/14/2020

The low-NOx regulation for heavy duty trucks proposed by California’s Air Resources Board (CARB) will present a significant challenge to truck, engine and aftertreatment system manufacturers. This regulation will include a new test cycle representative of low-load operation. With low-load cycles, NOx conversion by the SCR (selective catalytic reduction) system is limited primarily by the exhaust temperature; thus, thermal management will dominate development. Simulation can be used to examine different thermal management strategies, and to define high-level requirements for new components. In this study, modeling was used to investigate SCR performance on two different low-load cycles, including the one selected by CARB for the low-NOx regulation. First, the “thermal deficit” of the cycle was quantified using a constant heat input. Next, direct heating of the exhaust with a fuel mini-burner or an electric heater, using realistic controls, was simulated to determine their capability to

Uncertainty of the Ice Particles Median Mass Diameters Retrieved from the HAIC-HIWC Dataset: A Study of the Influence of the Mass Retrieval Method

2019-01-19836/10/2019

In response to the ice crystal icing hazard identified twenty years ago, aviation industry, regulation authorities, and research centers joined forces into the HAIC-HIWC international collaboration launched in 2012. Two flight campaigns were conducted in the high ice water content areas of tropical mesoscale convective systems in order to characterize this environment conducive to ice crystal icing. Statistics on cloud microphysical properties, such as Ice Water Content (IWC) or Mass Median Diameter (MMD), derived from the dataset of in situ measurements are now being used to support icing certification rulemaking and anti-icing systems design (engine and air data probe) activities. This technical paper focuses on methodological aspects of the derivation of MMD. MMD are estimated from PSD and IWC using a multistep process in which the mass retrieval method is a critical step.

Mitigation of Community Noise from a Vacuum Excavator Using Simulations

2019-01-14806/5/2019

Off-highway equipment operates in residential communities and must meet their radiated noise targets to be compliant with noise regulations and to be competitive in the marketplace. Traditional find and fix noise testing of late-stage prototype designs may cause launch delays, with intense time pressures that often result in missed opportunities to create excellent products with good value. Accurate simulation of noise from these machines allows noise targets to be assessed at each stage of product development, giving engineers time to develop low noise products without adding excessive manufacturing cost. Simulation of an early prototype of a new vacuum excavator showed excessive levels of radiated noise in two different frequency ranges. Further investigation of the simulation results of these two spectrum ranges indicated different noise mechanisms producing the excessive noise levels. An acoustic resonance was excited in the exhaust flow downstream of a silencer by highly vortical

Broadband Membrane-Type Acoustic Metamaterial Structures with Polymorphic Anti-Resonance Modes

2019-01-15746/5/2019

The researches indicate that rational design of membrane-type acoustic metamaterial (MAM) can make it have a high sound transmission loss (STL) at the anti-resonant frequency. Based on the principle of local resonance of acoustic metamaterials, this paper studied the coupling interactions between sound field and vibration modes, and designed four lightweight MAM structural units with different distributed harmonic oscillators, and then the anti-resonant behaviors of different units within the low frequency were gradually analyzed. The regulation mechanism of continuous polymorphic anti-resonance modes on broadening STL bandwidth was further revealed, and the STL characteristics have been verified within the low-frequency range by numerical simulation and experiments. The results show that the design of a single cross-shaped resonator can increase the diversity of anti-resonance modes and eliminate the node-circular-type resonance mode, then ensure the wider STL bandwidth.
