On 25 November 2004 the Civil Aviation Authority of New Zealand raised New Zealand's transition altitude from 11,000 to 13,000 feet (3,400 to 4,000 m) and changed the transition level from FL130 to FL150. [8] The transition level (TL) is the lowest flight level above the transition altitude. The table below shows the transition level according ...

Existing engines used on the Space Launch System are throttled to 109% power during normal flight, while new RS-25 engines produced for the Space Launch System are to be run at 111% throttle, [38] with 113% power being tested. [39] [40] These increases in throttle level made a significant difference to the thrust produced by the engine: [6] [27]
Starship flight test 8 was the eighth flight test of a SpaceX Starship launch vehicle. The launch tower successfully caught Booster 15 ; Ship 34 was destroyed before completing its planned flight, as during its initial burn four of the six engines experienced premature shutdowns that resulted in a loss of attitude control followed by a total ...
The DASS GN 1 engine concept. The DASS engine is a pre-cooled combined cycle propulsion concept that can produce thrust over a wide range of vehicle flight Mach numbers (rest to hypersonic). Derivatives of the engine can be used for propulsion of an SSTO vehicle, long-range missiles, and hypersonic transport aircraft. The engine is being ...
Most liquid engines use a bipropellant, consisting of two liquid propellants (fuel and oxidizer) which are stored and handled separately before being mixed and burned inside the combustion chamber. Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow ...
In October 2012, SpaceX publicly announced concept work on a rocket engine that would be "several times as powerful as the Merlin 1 series of engines, and won't use Merlin's RP-1 fuel". [58] They indicated that the large engine was intended for a new SpaceX rocket, using multiple of these large engines could notionally launch payload masses of ...
A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.
