GE Aerospace’s Post

What a journey on so many levels!!

At GKN Aerospace safety is our number one priority - and that applies to our future sustainable aviation technologies too! Peter Malkin from Newcastle University is a Partner in our H2GEAR programme, and gave a great presentation talking about how the hyperconducting cryo cooled power distribution can offer important safety and fault resilience functionality. He highlights the tendency to assume power distribution (high voltage, cryogenic or otherwise) is simple, but the full safe system functionality and scalability of power networks for electric aircraft is relatively under-studied. The #H2GEAR collaboration has considered these challenges from the start, exploring and modelling thousands of network configurations to identify and act on the few approaches that will ultimately deliver sustainable, scalable and safe flight! #hydrogen #netzero #innovation #technology #power #electrification

Meet Continental Aerospace Technologies’ new CD-170R, a 4-cylinder, Jet-A piston variant of its CD-170 engine. The 170-HP turbocharged power plant, specifically for rotorcraft applications, features state-of-the-art FADEC, resulting in lower fuel consumption and dual redundancy.

Pete Smith FRAeS encouraging the Advanced Engineering UK audience that Liquid Hydrogen will be on the next aircraft for Airbus, and need for the infrastructure and regulations is key, but so is collaboration to achieve so much in the 2035 timescales. Peter later explained that the Wright Brothers didn’t invent Concorde when questioned about Hydrogen Retrofit aircraft, suggesting they may pave a way for the larger aircraft- we need to learn about the materials and test them for liquid hydrogen, and this needs to happen before 2026 — U.K. Aerospace has a narrow window to sort out all the testing. #sustainableaviation Aerospace Technology Institute #liquidhydrogen #zeroemissions #zeroe #advancedengineering2023 #ae2023 #lh2

The Lockheed Martin SR-72's engine design is shrouded in secrecy, but here's what we can glean from publicly available information: Hypersonic Goal: The SR-72 aims to achieve hypersonic speeds exceeding Mach 6, requiring an engine that can function efficiently across vast speed ranges – subsonic, supersonic, and hypersonic. Combined Cycle Engine (likely): Experts believe the SR-72 will utilize a Turbine-Based Combined Cycle (TBCC) engine. This combines two engines: Turbine Engine: Provides power for low-speed flight and initial acceleration. Scramjet Engine: Takes over at high speeds for hypersonic flight. Scramjets function by using supersonic airflow for combustion, eliminating the need for bulky compressors, making them ideal for hypersonic speeds. Development Collaboration: Lockheed Martin reportedly collaborated with Aerojet Rocketdyne on a scramjet-based design for the SR-72. However, specifics remain classified. Challenges and Uncertainties: Developing a scramjet engine that seamlessly integrates with a turbine engine and functions efficiently across various speed regimes is a significant technical hurdle. There haven't been any official announcements about the SR-72's development progress since 2018, leading some to believe the project might be on hold or facing delays. Overall, the SR-72's engine design is a fascinating mystery. While the TBCC concept with a scramjet seems likely, specifics remain under wraps. The project's future development and timeline are also uncertain. #johnmoody #SR72
