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.

Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...
A derivative of the Europa XS kit plane, it serves both as a touring aircraft for private flyers and as a flight trainer. Subsequently, Discovery Aviation acquired the rights and in 2018 production of the aircraft (now named as the Discovery XL-2 ) resumed at the same Florida factory.

[note 2] Liquid-propellant rockets have a motor that feeds liquid propellant(s) into a combustion chamber. 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.
A flaw in the brazing of an RL10B-2 combustion chamber was identified as the cause of failure for the 4 May 1999 Delta III launch carrying the Orion-3 communications satellite. [ 14 ] The DIRECT version 3.0 proposal to replace Ares I and Ares V with a family of rockets sharing a common core stage recommended the RL10 for the second stage of the ...
Like the earlier Vari-Eze and Long EZ, the Berkut kneels with its nose gear retracted to prevent the aircraft from tipping over backwards when parked without a pilot in the front seat. Some early Berkuts utilized hydraulic nose-gear extension systems, but most have used an electro-mechanical jack-screw.
