A rotating detonation engine (RDE) [21] might propel airframes in hypersonic flight; on 14 December 2023 engineers at GE Aerospace demonstrated their test rig, which is to combine an RDE with a ramjet/scramjet, in order to evaluate the regimes of rotating detonation combustion. The goal is to achieve sustainable turbine-based combined cycle ...
SABRE (Synergetic Air Breathing Rocket Engine [4]) was a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air-breathing rocket engine. [5] [6] The engine is designed to achieve single-stage-to-orbit capability, propelling the proposed Skylon spaceplane to low Earth orbit.
Furthermore, this means that high-speed engines need to be made of materials that can survive extremely high temperatures. In practice, this inevitably makes the engines heavier and also reduces the amount of fuel that can be burned, to avoid melting the gas turbine section of the engine. This in turn reduces thrust at high speed.
The hypersonic engine for Quarterhorse joins similar initiatives to unlock the era of hypersonic flight, including the Air Force’s Project Mayhem, which hopes to deliver a hypersonic bomber in ...
The Department of Defense is hungry for all things hypersonic, including its new rocket engine. Here are the details. The Pentagon Is Obsessed With Hypersonics, Especially Its New Rocket Engine
The Silbervogel was the first design for a hypersonic weapon and was developed by German scientists in the 1930s, but was never constructed. [6]The ASALM (Advanced Strategic Air-Launched Missile) was a medium-range strategic missile program developed in the late 1970s for the United States Air Force; the missile's development reached the stage of propulsion-system testing, test-flown to Mach 5 ...
The engine to be used in the Hermeus aircraft adds a precooler to a standard Pratt & Whitney F100 [clarification needed].The precooler lowers the temperature of incoming air, preventing the melting of engine parts and allowing the engine to be more efficient.
Strictly speaking, hypersonic weapons are those that equal or exceed speeds equivalent to five times the speed of sound. But in modern usage, the term usually refers to two specific kinds of weapon.
