Burner Rig Testing of A500® C/SiC

There is growing interest in developing, testing, and deploying ceramic-matrix composites (CMCs) into commercial and military aerospace gas turbine engines due to their durability under extreme conditions and weight-savings potential. For military applications, the focus is on the afterburning section of the turbine engine, including the flameholder, augmentor liner, and both the convergent and divergent segments of the exhaust nozzle. These are demanding applications because of the high temperatures and rapid thermal cycles.

Advantages of Electropolishing for Penetrant Testing

It’s common, especially in the aerospace industry, for parts that are fracture critical to be Liquid Penetrant Inspected (LPI) prior to installation. Also known as Dye Penetrant Inspection (DPI) or simply Penetrant Testing (PT), this method is used to detect micro-cracks or other defects that could serve as an initiation site for failure. In order to properly execute a penetrant test, the surface of a metal part must be thoroughly clean of any debris, smeared metal, or any amorphous layer that may be hiding a hairline crack, thus yielding a false reading.

New Products: September 2018 Aerospace & Defense Technology

Pin Fin Heat Sinks

Advanced Thermal Solutions, Inc. (ATS) (Norwood, MA) has a family of Pin Fin heat sinks designed as cost-effective solutions for systems with adequate airflow. The high aspect ratio design enables ATS Pin Fin heat sinks to provide low thermal resistance from base to fins in systems where the airflow measures 200-plus LFM (linear feet per minute). The cross-cut design also allows the Pin Fin heat sinks to be effective in systems where airflow is ambiguous.

Designing a High-Speed Decoy Unmanned Aerial Vehicle (UAV)

Drone aircraft and their uses have been evolving quickly, supported by a great deal of ongoing research. One area of increasing interest is the decoy drone, designed to mimic the radar and heat signature of an actual aircraft. These drones are intended to confuse or mislead anti-aircraft defense systems. If operating as designed, one or more drones are launched from an actual aircraft as it enters airspace monitored by anti-aircraft systems. The system picks up the signature of the drones and attacks them while the actual aircraft can be hidden with the swarm of drones.

In-Flight Real-Time Avionics Adaptation

Avionics is a very restricting domain for obvious safety reasons. Along with miniaturization comes the idea of integration. More functionality on one spot requires a good management of privacy and congestion on shared platforms. This is why determinism is one of the keywords of avionics works. This led to protocols like ARINC653[1] assuring that multitask embedded programs respect a predictable policy applied by the operating system (OS). Another key protocol is ARINC664, which guarantees that multiple communicating systems efficiently share the network. These two protocols are pillars of the Integrated Modular Architecture (IMA) concept[2].

Warhead Life-Extension Program Passes Key Milestone

The program to extend the life of the W80 nuclear warhead recently achieved a significant milestone when the National Nuclear Security Administration (NNSA) gave passing grades to the plans to refurbish certain components and the proposed approach to developing component cost estimates. Passing the milestone confirms that the life extension program (LEP), dubbed the W80-4 LEP, remains on track. The refurbished warhead will be paired with a new cruise missile that is being developed in parallel by the U.S. Air Force, making this the first life extended warhead to be implemented in a new delivery system since the start of the Stockpile Stewardship Program more than 25 years ago.

Lawrence Livermore National Laboratory (LLNL) is the lead nuclear design agency, partnered with Sandia National Laboratories, which is the lead non-nuclear design agency. The work being carried out is driven by military requirements to pair the warhead with the new delivery system and improve weapon safety, security and operational logistics and maintain effectiveness without the need for additional explosive nuclear tests. First production of the W80-4 is planned for 2025.
