It is well recognized that weight savings within an airframe can result in significant lifetime cost savings and increased flight range. The transition of aluminum alloys to lighter, composite materials is an increasingly prevalent strategy to reduce weight on aircraft. This paper describes the application of a lightweight carbon fiber composite technology to aviation, engine start lithium batteries. The transition of lithium battery chassis technology from metal to composite introduces technical challenges not found with traditional battery chassis. Modern lithium batteries contain more than energy cells; common internal components include switch mode battery chargers, health and safety monitoring electronics, and even environmental control circuitry such as heaters. Consequently, electromagnetic interference disruption potential created by the electronics must be addressed.

Turbo-electric distributed propulsion (TeDP) for aircraft allows for the complete redesign of the airframe so that greater overall fuel and emissions benefits can be achieved. Whilst conventional electrical power systems may be used for smaller aircraft, much larger aircraft are likely to require the use of superconducting electrical power systems to enable the required whole system power density and efficiency levels to be achieved. The TeDP concept requires an effective electrical fault management and protection system. However, the fault response of a superconducting TeDP power system and its components has not been well studied to date, limiting the effective capture of associated protection requirements. For example, with superconducting systems it is the possible that a hotspot is formed on one of the components, such as a cable. This can result in one subsection, rather than all, of a cable quenching.

The crossing event of the blades of a coaxial counter-rotating rotor is a potential source of noise and severe blade loads. Blade crossings occur several times each rotor revolution. Most of the radial variation in the flow field can be efficiently captured by stacking the results of a 2-D analysis using two airfoils approaching each other at the appropriate relative Mach number and separation distance. Previously, this phenomenon was analyzed by simulating two airfoils passing each other at specified speeds and vertical separation distances, using the compressible Navier-Stokes solver OVERFLOW. The simulations explored thickness, circulation, and compressible effects. Results revealed the complex nature of the aerodynamic and fluid dynamic impulses generated by blade-blade interactions, with implications for aeroelastic loads and aeroacoustic sources.

Designed in Japan with exterior surfacing finalized at Honda’s California studio, the 2018 Accord is up to 176 lb (89 kg) lighter than the outgoing model, depending on trim level. Key technical features include two new turbocharged gasoline engines, the first use of a 10-speed automatic transaxle (Honda’s own 10AT) in front-drive sedan, and the return to the low-cowl/thin pillar body architecture.

AIR5479B
This SAE Aerospace Information Report (AIR) describes the performance of plating’s and coatings for landing gear that potentially provide environmental compliance benefits versus the current baseline processes. The hazardous systems addressed in this version of the document include cadmium plating, chromated primers, and high VOC (volatile organic compounds) topcoats. The AIR applies to landing gear structures and mechanisms for all types of civil and military aircraft. The potential replacements apply to both Original Equipment Manufacturer (OEM) hardware and overhaul of in-service landing gears.
