Abstract At hypersonic speed, severe aerodynamic heating is observed, and temperatures are too high to cool by radiation cooling; active cooling such as ablative cooling is helpful in this situation. ...A Computational Fluid Dynamics (CFD) simulation of a two-dimensional (2D) lifting body against thermally perfect air in a hypersonic region (Mach number, M > 5) is carried out for M = 5–9 to obtain a heat-transfer-minimized sweepback angle (ΛHT-min), at which heat transfer to the vehicle is minimum.

This Recommended Practice is intended to outline the design, installation, testing, and field maintenance criteria for a high temperature metal pneumatic duct system, for use as a guide in the aircraft industry. These recommendations are to be considered as currently applicable and necessarily subject to revision from time to time, as a result of the rapid development of the industry.

This SAE Aerospace Information Report (AIR) covers the field of civilian, commercial and military airplanes and helicopters. This summary of tail bumper design approaches may be used by design personnel as a reference and guide for future airplanes and helicopters that require tail bumpers. Those described herein will consist of simple rub strips, structural loops with a wear surface for runway contact, retractable installations with replaceable shock absorbers and wear surfaces and complicated retractable tail landing gears with shock strut, wheels and tires. The information will be presented as a general description of the installation, its components and their functions.

Abstract Jet engine hot parts (e.g., jet nozzle) are a crucial source of aircraft’s infrared (IR) signature from the rearview, in 1.9-2.9 μm and 3-5 μm bands. The exhaust nozzle design used in a jet aircraft affects its performance and IR signature (which is also affected just by performance) from the engine layout. For supersonic aircraft (typically for M ∞ > 1.5), a converging-diverging (C-D) nozzle is preferred over a convergent nozzle for optimum performance. The diverging section of the C-D nozzle has a full range of visibility from the rearview; hence, it was not considered a prudent choice for low IR observability. This theoretical study compares the IR signature of the C-D nozzle with that of the convergent nozzle from the rearview in 1.9-2.9 μm and 3-5 μm bands for the same thrust.

This section presents the basic equations for computing ice protection requirements for nontransparent and transparent surfaces and for fog and frost protection of windshields. Simplified graphical presentations suitable for preliminary design and a description of various types of ice, fog, frost, and rain protection systems are also presented.

Austrian telematics company, Dolphin Technologies GmbH, has created a new cryptocurrency that could lead to less mobile phone-related traffic accidents. The company’s Mobilio app rewards drivers with points when they ignore their mobile phones while driving.

Swiss air navigation service provider, skyguide, AirMap, Inc. – the leading global airspace intelligence platform for drones, and the Swiss Federal Office of Civil Aviation (FOCA) have deployed the Swiss U-space flight information management system (FIMS) for small unmanned aircraft systems (UAS) and drones.

Helicopter manufacturer and Textron Inc. subsidiary, Bell Flight, is adding a new piece of standard equipment to its Bell 407GXi single-engine, civil utility helicopter program: bird-deterring, pulsing lights.

Originally published in 1995, now updated and expanded with new specifications, this seminal work focuses on the development of Allied aircraft engines that helped turn the tide of World War II.

Lockheed Martin's Auto-GCAS uses terrain mapping, geolocation, and automation to detect and avoid potential ground collisions in case of pilot spatial disorientation. The technology was initially fielded on the F-16 Fighting Falcon, but will now save an estimated 26 crashes over the course of F-35 service life.

Viziblezone Ltd.’s vehicle-to-pedestrian (V2P) solution to autonomous vehicles or “self-driving cars” is now capable of detecting pedestrians at distances of up to 150 meters (nearly 500 feet) – even when those pedestrians are standing behind objects that block line-of-sight.

When a four-alarm fire started burning at a Santa Clara, California construction site down the street from Impossible Aerospace Corporation, the startup sent one of its US-1 unmanned aerial vehicle (UAV) or drone equipped with thermal and optical sensors to help ground crews battle the blaze.

The test was conducted to better understand the dynamic forces on an aircraft and its passengers during a crash landing. Findings form the event will support a new FAA performance-based rule that will simplify aircraft certification by eliminating or minimizing the use of special conditions.

Newer, more capable fifth-generation aircraft platforms and systems are outgrowing even the largest U.S. Air Force training ranges – and the service believes modern simulators and virtual reality may be the answer.
