precooled การใช้

• The atoms are usually precooled using the Doppler laser cooling.
• Once precooled below this temperature, helium can be liquefied through expansion cooling.
• The development of this engine lost focus in favor of the new hypersonic precooled turbojet engine ( PCTJ ).
• Precooled jet engines are jet engines with a heat exchanger at the inlet that cools the air at very high speeds.
• White's preliminary results, published in June in the journal Multiple Sclerosis, found precooled patients walked better and felt better.
• At around the same time, the HOTOL tried to use precooled jet engine technology, but failed to show significant advantages over rocket technology.
• Types of air breathing engines proposed for spaceplanes include scramjet, liquid air cycle engines, precooled jet engines, pulse detonation engine and ramjets.
• Alan Bond brought a precooled jet engine design he had invented to the HOTOL project, and this became the Rolls Royce RB545 rocket engine.
• The proposed engine for the vehicle is not a scramjet, but a jet engine running combined cycles of a precooled jet engine, rocket engine and ramjet.
• Originally the key technology for this type of precooled jet engine did not exist-the required heat exchanger was about ten times lighter than the state of the art.
• Precooled jet engine mentions the concept of cooling the intake air using the fuel, but apparently this isn't in production yet . talk ) 01 : 52, 23 August 2012 ( UTC)
• In addition, a successful static test firing of the ATREX, an experimental precooled jet engine that works as a turbojet at low speeds and a ramjet up to Mach 6.0 occurred in 1992.
• In Britain, the Reaction Engines A2 has been proposed to use the thermodynamic properties of liquid hydrogen to achieve very high speed, long distance ( antipodal ) flight by burning it in a precooled jet engine.
• In 2010, the NMSU Physical Sciences Laboratory has secured a study contract with Reaction Engines Limited, a British aerospace company that is developing technology for an airbreathing single-stage to orbit, precooled air turboramjet based spaceplane.
• Interest in precooled engines saw a brief emergence in the UK in 1982, when Alan Bond ( formerly of the Blue Streak missile project ) created a LACE-like design he called "'SATAN " '.
• Other, reusable turbojet-like designs like Skylon which uses precooled jet engines up to Mach 5.5 before employing rockets to enter orbit appears to have a mass budget that permits a larger payload than pure rockets while achieving it in a single stage.
• The "'ATREX "'engine ( "'Air Turbo Ramjet Engine with eXpander cycle "') developed in Japan is an experimental precooled jet engine that works as a turbojet at low speeds and a ramjet up to mach 6.0.
