A multi-axis thrust vectoring engine nozzle in motion. Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.
Thrust vectoring for many liquid rockets is achieved by gimbaling the whole engine. This involves moving the entire combustion chamber and outer engine bell as on the Titan II's twin first-stage motors, or even the entire engine assembly including the related fuel and oxidizer pumps. The Saturn V and the Space Shuttle used gimbaled engines. [1]
Active flow control by MHD force fields on the contrary involves a direct and imperious action of forces to locally accelerate or slow down the airflow, modifying its velocity, direction, pressure, friction, heat flux parameters, in order to preserve materials and engines from stress, allowing hypersonic flight.
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
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.
Both these missions are funded by the US Defense Advanced Research Projects Agency to help develop hypersonic technologies and to demonstrate its effectiveness. [6] Under the original plan, HTV-1 was to feature a hypersonic lift-to-drag ratio of 2.5, increasing to 3.5-4 for the HTV-2 and 4-5 for the HTV-3. The actual lift-to-drag ratio of HTV-2 ...
What are hypersonic missiles? Hypersonic missiles, like the Kinzhal (Dagger) rockets allegedly being deployed by the Russian Air Force, are thought to represent the next generation of arms because ...
