Test pilots began flying the Sierra Nevada-Embraer A-29 Super Tucano and Textron Aviation AT-6B Wolverine, kicking off phase two of the USAF Light Attack Experiment.

As Lockheed Martin Aeronautics ramps up production of its fifth-generation F-35 fighter program, it is also looking to improve manufacturing efficiency. This month, the company has licensed Ubisense SmartSpace for deployment at its Fort Worth, TX facility.

Larger airframes drove the development of electrical systems, capable of quickly and reliably starting the new higher power engines. These soon gave rise to the need for engine-mounted electrical generators as the primary source of in-flight power for the electrical loads and onboard recharging of the aircraft battery system. Of all the backup power sources, batteries represent the most common means of storing energy for auxiliary or emergency power requirements. It is not unusual for a typical commercial airliner, such as a B-737 or A-320, to have dozens of batteries on board. Over time, multiple battery chemistries were put to the test and the industry is still working on the optimal option. The lithium-ion technology has been gaining acceptance, with some important aspects to be considered: the application type, basic safety requirements and the presence or absence of humans on the vehicle.

Vapor Pressure Data and Analysis for Selected Organophosphorous Compounds: DIBMP, DCMP, IMMP, IMPA, EMPA, and MPFA Determining the thermophysical properties of chemical warfare agent simulants can help evaluate the performance of defensive equipment.

On June 28, 2017, days ahead of the July 2017 U.S. Air Force light attack aircraft experiment, the Senate Armed Services Committee passed a preliminary vote for a proposed annual defense budget that included $1.2 billion for “a fleet of Light Attack/Observation aircraft.”

Although the lightweight, supersonic T-38 has been the staple advanced jet trainer for the U.S. Air Force and U.S. Naval Test Pilot School for more than 55 years, the aircraft is expected to be replaced by a new trainer that can better transition pilots into fourth- and fifth-generation fighters.

Other technologies and “building blocks” above and beyond the new stealth bomber the USAF is looking to harvest include autonomous learning systems, human-machine collaboration, and smart weapons

Autonomous vehicles: impact on society Self-driving technology offers plenty of promise, but not everything about autonomous vehicles will be a panacea. Crankshaft reliability by integrated design, simulation, and testing This testing method is proven and beneficial for the design and development of the crankshaft and could be applied to other critical engine components, thereby extending to system reliability. New Engines 2016 Highlighting the design, engineering, and technologies inside some of the most competitive gasoline and light-duty diesel ICEs. Touch and go Avionics developments are changing life in the cockpit and at airborne work stations. Improving heavy-duty engine component efficiencies Cylinder deactivation can improve fuel economy by using a reduced number of cylinders that operate at higher loads and thermal efficiency, while other cylinders are turned off, when the engine operates at partial load conditions.

The T-50A was developed jointly by Lockheed Martin and Korea Aerospace Industries (KAI) to replace the T-38 and train pilots to fly fifth-generation aircraft such as the F-22 and F-35.

Touch and go Avionics developments are changing life in the cockpit and at airborne work stations Sandwich cores for the future Decreasing weight while increasing strength is always critical, from airliners to future space missions to Mars. Research in sandwich cores today may lead to radical improvements in the future.

The company continues to commit and breathe new life into its 40-year old fourth-generation fighter aircraft.

At high angles of attack, the flow over a swept wing generates counter-rotating vortical features. These features can amplify into a nearly sinusoidal fluctuation of velocity components. The result is excitation of twin-fin buffeting, driven at clearly predictable frequencies, or at nearby lock-in frequencies of the fin structure. This is distinct from the traditional model of fin buffeting as a structural resonant response to broadband, large-amplitude excitation from vortex core bursting. Hot-film anemometry was conducted ahead of the vertical fins of a 1:48 scale model of the F-35B aircraft, in the angle of attack range between 18 and 30 degrees. Auto spectral density functions from these data showed a sharp spectral peak in the flow ahead of the fins for angles of attack between 20 and 28 degrees. Small fences placed on the top surface of the wing eliminated the spectral peak, leaving only a broadband turbulent spectrum.

This document defines Controller Area Network (CAN) interface standard. It defines the physical layer provisions to maintain compliance with ISO 11898. The scope of Supplement 3 is limited to correcting the high integrity message CRC calculation and providing additional guidance to support interoperability. This includes the definition of a periodic health status message, functional status reporting, peer-to-peer message structure, and quiet bus behavior.
