In this paper, we describe an innovative V&V approach using the SCADE product, enabling significant reduction of effort while preserving compliance with DO-178C/DO-331. This new approach relies on a unique capability: automatic generation of Low-Level Tests. Details about savings will be provided to show how we can reduce costs, speed up certifications, and bring products to the market faster. We will conclude by summarizing the actual benefits and describing ongoing work to bring other savings in the future.
Civil and military rotorcraft operators desire enhanced capabilities from their vehicles in terms of mission efficiency, effectiveness, productivity, and availability. A critical element of this challenge is associated with providing cold weather availability. Currently, cold weather operations are enabled by regulatory actions leading to Limited Approvals, Qualifications, Clearances, and Restrictions. Cold weather certification (clearance of a new aircraft) and continuing airworthiness (maintaining effectiveness of fielded aircraft) are data driven processes. This work provides guidance on an Icing Encounters Survey (IES) based data gathering method supporting continuing airworthiness organizations in improving fleet safety and capabilities during cold weather operations.
The scope of this report will document the various voltage levels and provide a rational for each level as discussed and agreed to in the AE-7 committee.
Since certifying the Bell 505 in December 2016, customers on six continents have received delivery of 250 of these light, single-engine aircraft. In three years the worldwide fleet logged more than 35,000 flight-hours, a testament to the Bell 505's customer experience - not only with the aircraft, but with delivery and service. In getting to the 250th delivery, the paper discusses the efforts taken to meet market demand, provide custom finishing, offer kit integration, and even take on additional envelope expansion. Numerous configurations and kits were made available a short time after initial certification, allowing Bell 505 customers to take full advantage of the aircraft capability in a timely manner. The challenges of meeting market demand and transitioning from low rate production to full rate production requires a team effort and this paper shows how it was done for the 505.
ABSTRACT The development of Bell's third-generation tiltrotor, the V-280, places great focus on achieving low cost and robust design simplicity and is demonstrated on the Joint Multi-Role (JMR) Air Vehicle Concept Demonstrator (AVCD). The design and manufacture of the V-280 AVCD wing structure is an example that achieves significant recurring and development cost savings through the infusion of Design for Manufacturing (DFM) principles, advanced materials, robust manufacturing processes, and low-cost developmental tooling. To drive simplicity through all aspects of the design, the V-280 AVCD wing employs a straight, constant section profile with no forward sweep or upward dihedral. Wing skins, spars, and ribs utilize a broad goods layup technique that favors large fabric ply shapes over highly tailored tape plies. This approach has yielded significant reduction in fabrication labor hours (via increased composite material application rates) and has resulted in reduced scrap material
