A NASA employee standing between two Raptor 2 Vacuum engines (background) and a Raptor 2 sea-level (foreground). The streamlined design is due to the reduced parts visible above the engine nozzles. Raptor 2 is a complete redesign of the Raptor 1 engine. [79] The turbomachinery, chamber, nozzle, and electronics were all redesigned.
Raptor is a family of methane/liquid oxygen rocket engines under development by SpaceX since the late 2000s, [2] although LH2/LOX propellant mix was originally under study when the Raptor concept development work began in 2009. [15] When first mentioned by SpaceX in 2009, the term "Raptor" was applied exclusively to an upper stage engine ...
This template has provisions for four sections: General characteristics, performance, armament, and avionics. What follows is list of the parameters that appear in each section, and specialised instructions for their use where necessary.
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
The non-cryogenic N 2 O 4 /UDMH engine RD-253 using staged combustion was developed by Valentin Glushko circa 1963 for the Proton rocket. After the abandonment of the N1, Kuznetsov was ordered to destroy the NK-33 technology, but instead he warehoused dozens of the engines. In the 1990s, Aerojet was contacted and eventually visited Kuznetsov's ...
The Jonker JS-3 Rapture is a glider built of glass-fibre, carbon fibre and Kevlar. It has full-span flaps and can be operated with a wingspan of either 15 m (49.2 ft) or 18 m (59.1 ft). [2] [3] [4] The manufacturer is Jonker Sailplanes of Potchefstroom South Africa, founded in 2004 by two brothers, Attie and Uys Jonker.
Table tennis regulations approved by the International Table Tennis Federation (ITTF) allow different surfaces on each side of the paddle for varying amount of spin (including nullifying it) or speed. [2] For example, a player may have a spin-heavy rubber on one side of their paddle, and no spin on the other side.
