Through a new teaming agreement signed at Le Bourget during the 53rd International Paris Air Show, Northrop Grumman’s scramjet combustors will find a new home on the Raytheon Company’s air-breathing hypersonic weapons.

Lockheed Martin successfully flight tested the AGM-183A Air-Launched Rapid Response Weapon (ARRW) on a U.S. Air Force Boeing B-52 Stratofortress. The captive carry flight – announced during the 2019 International Paris Air Show – marks Lockheed Martin’s most recent demonstration of hypersonic technology development.

Almost exactly seven months after Unites Technologies Corporation (UTC) completed its acquisition of Rockwell Collins (now Collins Aerospace), the aerospace conglomerate announced its merger with the Raytheon Company.

ONR Short Pulse Research, Evaluation and non-SWaP Demonstration for C-sUAV Study Research project is designed to map small unmanned aerial vehicle (sUAV) effects space, empirically and by simulation, as a function of high power microwave (HPM) waveform to develop effective countermeasures.

Magneti Marelli's 'Smart Corner' technology aims to reduce cost, complexity and mass by integrating key vehicle sensors seamlessly into a vehicle's lighting modules. Supersonic Spy Drone To light off its ramjet engine, the 2,300-mph D-21 needed a blindingly-fast launch platform.

Several prototypes are currently targeting urban air mobility (UAM) platforms, such as air taxis, and revolutionary aircraft models like next-generation commercial supersonic aircraft. Add to this autonomous swarm technologies, enabling manned-unmanned teaming, and systems for future vertical lift and it’s clear that the technology wave can easily become overwhelming.

The fluid flow treated in this section is isothermal, subsonic, and incompressible. The effects of heat addition, work on the fluid, variation in sonic velocity, and changes in elevation are neglected. An incompressible fluid is one in which a change in pressure causes no resulting change in fluid density. The assumption that liquids are incompressible introduces no appreciable error in calculations, but the assumption that a gas is incompressible introduces an error of a magnitude that is dependent on the fluid velocity and on the loss coefficient of the particular duct section or piece of equipment. Fig. 1A-1 shows the error in pressure drop resulting from assuming that air is incompressible. With reasonably small loss coefficients and the accuracy that is usually required in most calculations, compressible fluids may be treated as incompressible for velocities less than Mach 0.2.

Artificial intelligence (AI) and machine learning (ML) will continue to bring about significant changes in aircraft cockpits and help move commercial, military, and general and business aircraft from automated to autonomous systems, affirm subject-matter experts at Wind River in Alameda, California, and Collins Aerospace in Cedar Rapids, Iowa.

Visualized images show that strong knocking combustion results from secondary autoignition and subsequent supersonic reaction wave propagation. Further analysis on thermodynamic trajectories shows that the secondary autoignition may closely correlate with the negative temperature coefficient behavior controlled by low-temperature chemistry.

Detonation and supersonic reaction front occur under ultra-lean conditions at effective temperatures from 850 K to 900 K and effective pressures more than 20 bar, which should be suppressed for lean-burn engine application.

Under the same valve lift condition, with the increase of relative pressure difference, the discharge coefficient decreases slightly in subsonic state and decreases sharply from subsonic state to supersonic state, but the mass flow rate increases slightly. The optimum ratio of valve lift and valve seat diameter is related to relative pressure difference, it increases first and then keeps constant with the increase of relative pressure difference.

Supersonic aircraft technology experts – including engineers, scientists, and executives – set the record straight on supersonic commercial transport, addressing attainability, reliability, safety, unsettled topics, technology needs, and next steps in an interactive panel discussion at SAE International’s AeroTech Americas. ...Supersonic aircraft technology experts – including engineers, scientists, and executives – set the record straight on supersonic commercial transport, addressing attainability, reliability, safety, unsettled topics, technology needs, and next steps in an interactive panel discussion at SAE International’s AeroTech Americas.

In the “What’s Next for Aerospace and Defense: A Vision for 2050” study, AIA, New York City-based McKinsey & Company, and other industry partners reveal a comprehensive 30-year, Industry 4.0 forecast of air travel and spaceflight based on improvements in automation and digitization, next-generation materials, alternative energy sources and storage, and increased data throughput.

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.

According to the Russian Ministry of Industry and Trade, the Moscow-based United Aviation Corporation (UAC) will begin development on a supersonic passenger aircraft by 2022. The aircraft, backed by Russian President Vladimir Putin, will be based on the supersonic Tupolev Tu-160 heavy strategic bomber which first flew in 1981. ...The aircraft, backed by Russian President Vladimir Putin, will be based on the supersonic Tupolev Tu-160 heavy strategic bomber which first flew in 1981.

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.

In order to help the next generation of entrepreneurs enter that market, Boulder, Colorado-based Techstars and Paris-based Starburst Aerospace have joined forces to start a new Los Angeles-based business accelerator for space technology companies.
