This SAE Aerospace Recommended Practice (ARP) provides guidance for substantiating the airworthiness of aircraft engine components. Generally these components are associated with the engine control system, the system or systems that allow the engine to provide thrust or power as demanded by the pilot of the aircraft while also ensuring the engine operates within acceptable operating limits. But these components may also include hardware and systems associated with engine lubrication, engine or aircraft hydraulic or electrical systems, aircraft environmental control systems, thrust reverser control, or similar aircraft or engine propulsion system functions. This paper develops the concept of using a 26 item matrix of environmental conditions for evaluating aircraft engine component airworthiness. This approach is compatible with current practices used in the industry and has been accepted by engine certification authorities as part of engine certification programs.

Bye Aerospace is looking at OXIS Energy Ltd.’s lithium-sulfur (Li-S) battery cell technology to power its future aircraft and air-taxi or “urban air mobility” (UAM) designs. The companies are launching the initial phase of an advanced, high-voltage, lightweight Li-S battery pack development program for aerospace applications.

Two members of DCS Corp – Mark Wilkins and Finley Barfield – won the highly distinguished Robert J. Collier Trophy by the National Aeronautic Association for their work on the Air Force Research Laboratory (AFRL) Automatic Ground Collision Avoidance System (Auto-GCAS) team.

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.

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.

Under the contract, Raytheon will design, develop, produce, and sustain active electronically scanned array (AESA) radar systems for the U.S. Air Force’s entire B-52 long-range strategic bomber fleet, keeping the nearly 65-year-old aircraft mission ready through 2050 and beyond.

The Oshkosh, Wisconsin-based kit aircraft manufacturer is developing a two-seat variant of its SubSonex JSX-2 personal jet. The SubSonex JSX-2T is designed to be the lowest cost jet trainer ever built and the company hopes that it will lead to further interest in its single-seat JSX-2.

The Boeing Company is kicking off a new round of flight-testing to research approximately 50 technology projects related to safety, environmental sustainability, and passenger experience. More than a dozen partners are participating in the 2019 program.

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.

SAE International has published a new recommended practice for assessing the amount of nonvolatile particulate matter (nvPM) that exits aircraft engine exhaust nozzles – ARP6481: Procedure for the Calculation of Non-Volatile Particulate Matter Sampling and Measurement System Losses and System Loss Correction Factors

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.

Curtiss-Wright Corporation’s Fortress line of combined cockpit voice recorders (CVRs) and flight data recorders (FDRs) are now have European Technical Standard Order (ETSO) approval. The devices, commonly referred to as “black boxes,” will surpass the requirements of an upcoming 2021 European Union Aviation Safety Agency (EASA) mandate that requires CVRs are capable of recording for up to 25 hours per flight.

The X-59 utilizes a long and slender airframe to achieve supersonic speeds without causing a high decibel sonic boom. The unconventional design precludes the use of a forward-looking window or viewport. Collins Aerospace is providing a dual multi-spectral enhanced vision system to give pilots a forward view of the airspace.

This critical milestone comes after a rigorous review, called “Key Decision Point-C (KDP-C),” that confirmed NASA’s continued support of the X-59 in terms of funding. It establishes an achievable development timeline for NASA’s first piloted full-size X-plane in more than three decades.

Turboelectric aircraft propulsion and boundary layer ingesting propulsors may be a breakthrough technology for more-efficient air travel. Researchers are currently uncovering unforeseen hurdles to deploying the technology, but that’s not a bad thing. It’s just part of development.

On September 28, a day after the first Lockheed Martin F-35B combat strike, an F-35B stationed at USMC Air Station Beaufort crashed a short distance from the base. The aircraft was part of the 2nd Marine Aircraft Wing belonging to Marine Fighter Attack Training Squadron 501.

PTN has now evolved into an open call to individuals with backgrounds in aerospace, education, and technology to submit goal training solutions ranging from new ideas to highly-mature solutions that could help the USAF facilitate pilot training.

The oldest Lockheed Martin F-22 Raptor in the United States Air Force – tail number 91-4006 – just came out of retirement and took to the skies. It will now be used as a flight sciences aircraft, which will be an integral part of F-22 fleet modernization.

Pratt & Whitney was awarded the contract modification by the U.S. Air Force Life Cycle Management Center for the Adaptive Engine Transition Program. Through AETP, Pratt & Whitney was tasked with designing, fabricating, integrating, and testing complete, flight-weight adaptive engines – the contract modification allocates funding for “risk reduction” activities related to adaptive engine development.

Together, the companies will develop customized lightweight material systems and advanced manufacturing processes, such as metal additive manufacturing – also known as 3D printing – to advance current and next-generation aerospace and defense solutions, including new structures and systems not currently in existence.
