ABSTRACT The complexity of ground vehicle mission systems has evolved significantly over the last few years resulting in over-taxed platforms with federated mission suites. Department of Defense (DoD) is pursuing platform evolution toward integrated mission suites. Opportunities exist to apply aspects of previously developed methodologies from the aviation sector to ground platforms. This paper describes the parallels of the evolution of aviation platforms with the similarities to ground platforms. Solutions from the military aviation community will be discussed that could reduce development risks, schedules and costs and improve mission capabilities for ground applications. Specific discussion will be on opportunities and techniques to transition performance driven, high cost, low volume technologies into mission suitable and affordable high volume solutions. Discussion of the feedback opportunities into the aviation community will be addressed. This paper is not intended to be a

TBMG-5084906/01/2024

Used lithium-ion batteries from cell phones, laptops, and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. The current state of the art methods can pose environmental challenges and be difficult to make economical at the industrial scale.

Acoustic Evaluation of Fiber Based Materials for Engine Bay Applications

2025-01-011505/05/2023

A newly formulated fiber-based material was developed to offer a cleaner, recyclable alternative to foam-based vehicle acoustic products. The fiber-based material was designed to be used in multiple vehicle acoustic applications, with different blends of the material available depending on the application. It performs well as an engine bay sound absorber due to its high heat tolerance and good absorption performance. A study was conducted to evaluate the sound absorption performance of this fiber-based material, specifically the engine bay blends, in comparison to that of current foam-based products. The results from this study show that the sound absorption performance of this new fiber-based material can match that of current foam-based materials while providing a recyclable product unlike the foam.

The emergence and dominance of Lithium-ion (Li-ion) batteries in markets such as consumer electronics, electric vehicles, and renewable energy storage are driving enormous interest in the battery sector. The growing demand is generating a huge number of spent Li-ion batteries, thereby urging the development of cost-effective and environmentally sustainable recycling technologies to manage end-of-life batteries.

Pre-Treatment Solution for Water Recovery

TBMG-3959508/01/2021

The Pre-Treatment Solution for Water Recovery was developed by NASA Johnson to increase the amount of potable water recovered from the International Space Station’s urine processor assembly system. Turning wastewater, urine, or seawater into potable water requires three important steps: 1) pre-treatment, 2) distillation or membrane filtration, and 3) transport and storage of potable water and brine. This solution is added during the first step, consequently improving the next steps in the process primarily by reducing the formation of solid precipitates.

Process Turns Sand and Plant Materials into a Water Filtration Tool

TBMG-3581901/01/2020

According to the United Nations, 2.1 billion people lack access to safely managed drinking water services and the majority live in developing nations. A process was developed that uses sand and plant materials readily available in many developing nations to create a cheap and effective water filtration medium called “f-sand.” F-sand uses proteins from the Moringa oleifera plant, a tree native to India that grows well in tropical and subtropical climates. The tree is cultivated for food and natural oils, and the seeds are already used for a type of rudimentary water purification; however, this traditional means of purification leaves behind high amounts of dissolved organic carbon (DOC) from the seeds, allowing bacteria to regrow after just 24 hours. This leaves only a short window in which the water is drinkable.

Spray Parameters of Fuel Blends of Recycled Lubricating Oil and Diesel

2018-01-169309/10/2018

The use of alternative fuels consisting of mineral and synthetic waste substances such as recycled lubricating oil blended with diesel is a measure to mitigate the environmental impact of the fossil fuels. However, to inject these fuel blends into contemporary engines without changes to their components, it must maintain or improve the fuel injection characteristics compared to neat diesel, in order to maintain or improve the engine performance. In the present research, the spray parameters of injected fuel, such as length, angle and atomization particle diameter in terms of the Sauter mean diameter (SMD), are modeled depending on the characterization of different concentration of the recycled lubricating oil blended with diesel. It was found that the same nozzle geometry of the injectors can provide an equivalent fuel spray performance for different concentrations of these alternative fuel blends, and that the increase of the recycled lubricating oil in the fuel blend reduced the wear

Topology Control in Aerial Multi-Beam Directional Networks

TBMG-2765810/01/2017

In multi-beam directional networks, nodes are able to simultaneously transmit to all neighbors or receive from all neighbors. This spatial reuse allows for high throughputs, but in dense networks can cause significant interference. Topology control (i.e., selecting a subset of neighbors to communicate with) is vital to reduce the interference. Good topology control balances the number of links utilized to achieve fewer collisions while maintaining robust network connectivity.

Automotive A/C Servicing – Refrigerant Flushing of a Failed A/C System

2017-01-016703/28/2017

The failure of an A/C system often results in the introduction of contaminants to the A/C system. The sources of the contaminants include debris from damaged components and debris from the surrounding environment. Returning the A/C system to service requires the removal of these contaminants from any reused components. The recommended approach to cleaning contaminated components and systems is to flush with a solvent flushing machine. Previous internal studies have concluded that solvent flushing will remove all contaminants, restoring component and system performance. Many commercial refrigerant recovery and recharge machines include a refrigerant “flush” feature which can flush oil from the system and components with the systems refrigerant. The effectiveness of using the “flush” feature of a refrigerant recovery and recharge machine with an added in-line filter to remove contaminants is investigated. One gram of Arizona Test Dust is introduced to the suction line of an automotive A

Powder Reuse and Its Effects on Laser Based Powder Fusion Additive Manufactured Alloy 718

2016-01-207109/20/2016

Laser Based Powder Bed Fusion, a specific application of additive manufacturing, has shown promise to replace traditionally fabricated components, including castings and wrought products (and multiple-piece assemblies thereof). In this process, powder is applied, layer by layer, to a build plate, and each layer is fused by a laser to the layers below. Depending on the component, it appears that only 3-5% of the powder charged into the powder bed fusion machine is fused. Honeywell’s initial part qualification efforts have prohibited the reuse of powder. Any unfused powder that exits the dispenser (i.e., surrounds the build or is captured in the overflow) is considered used. In order for the process to be broadly applicable in an economical manner, a methodology should be developed to render the balance of the powder (up to 97% of the initial charge weight) as re-usable. Though multiple manufacturers may be re-using powder, there is no industry standard methodology or practice for powder

Ignition Delay Correlation for Engine Operating with Lean and with Rich Fuel-Air Mixtures

2016-01-069904/05/2016

An ignition delay correlation encompassing the effects of temperature, pressure, residual gas, EGR, and lambda (on both the rich and lean sides) has been developed. The procedure uses the individual knocking cycle data from a boosted direct injection SI engine (GM LNF) operating at 1250 to 2000 rpm, 8-14 bar GIMEP, EGR of 0 to 12.5%, and lambda of 0.8 to 1.3 with a certification fuel (Haltermann 437, with RON=96.6 and MON=88.5). An algorithm has been devised to identify the knock point on individual pressure traces so that the large data set (of some thirty three thousand cycles) could be processed automatically. For lean and for rich operations, the role of the excess fuel, air, and recycled gas (which has excess air in the lean case, and hydrogen and carbon monoxide in the rich case) may be treated effectively as diluents in the ignition delay expression.

Laboratory Test Means Scalable to the Test

2015-01-254609/15/2015

To perform a complete aircraft certification plan, civil aviation test centres use specific flight test installations and ground test means. In this scope tests specialists operate ground test means which have a generic name Laboratory Tests Means (LTM) to validate aircraft functions. Today these functions are becoming more and more complex, moreover certification deadlines and tests campaign costs are becoming increasingly challenging and demand LTM use optimization. In this context current LTM development approach is no longer suitable to cover these new constraints. Currently LTMs start to be designed when testing strategy for a new aircraft is defined and design is quite specific. Drawbacks of such an approach are: tunnel effect for LTM development, no simple sharing of testing resources, LTM reuse is not easy, LTM upgrade requires re-engineering and many LTMs have to be maintained even if only partially used. As a result future LTMs shall be scalable to the tests and tests shall
