Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum. RL10 versions were produced for the Centaur upper stage of the Atlas V and the DCSS of the Delta IV. More versions are in development or in use for the Exploration Upper Stage of the Space Launch System and the Centaur V of the Vulcan rocket. [2]
The rocket and its engines are developed by Blue Origin. The first stage uses BE-4 engines, and the second stage uses the hydrolox BE-3U. Terran 1 had a failed orbital launch attempt on its maiden flight on 22 March 2023, and the development of the rocket was terminated. The rocket, developed by Relativity Space, uses the Aeon 1 engine.
The Centaur is a family of rocket propelled upper stages that has been in use since 1962. It is currently produced by U.S. launch service provider United Launch Alliance, with one main active version and one version under development.
Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
This stage was technically referred to as the "Extra-Extended Long Tank Thor", a derivative of the Thor ballistic missile [24] as were all Delta rockets until the Delta IV. The RS-27 used on the 6000-series Delta II produced 915 kN (206,000 lbf) of thrust, [25] while the upgraded RS-27A used by the 7000-series produced 1,054 kN (237,000 lbf). [26]
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
The Hazen–Williams equation has the advantage that the coefficient C is not a function of the Reynolds number, but it has the disadvantage that it is only valid for water. Also, it does not account for the temperature or viscosity of the water, [ 3 ] and therefore is only valid at room temperature and conventional velocities.
