precooler การใช้

• Previous versions of precoolers such as HOTOL put the hydrogen fuel directly through the precooler.
• The cooling system for MIRI includes a Pulse Tube precooler and a Joule-Thomson Loop heat exchanger.
• In April 2012, REL announced that the first phase of the precooler test programme had been successfully completed.
• SABRE inserts a helium cooling loop between the air and the cold fuel to avoid problems with hydrogen embrittlement in the precooler.
• The'hot'helium from the air precooler is recycled by cooling it in a heat exchanger with the liquid hydrogen fuel.
• The company's current research effort is focused on precooler heat exchanger technology, with additional funding gained from the sale of consultancy.
• The RB545's precooler had issues with embrittlement, excess liquid hydrogen consumption, patents and the Official Secrets Act, so Bond developed SABRE instead.
• The dramatic cooling of the air created a potential problem : it is necessary to prevent blocking the precooler from frozen water vapour and other air fractions.
• The key design feature for the Scimitar engines is the precooler, which is a heat exchanger that transfers the heat from the incoming air into the hydrogen fuel.
• This research may have inspired the British HOTOL program, which rather than airbreathing to high hypersonic speeds as with NASP, proposed to use a precooler up to Mach 5.5.
• The "'R . W . Estes Celery Company Precooler Historic District "'( also known as the Nelson & Company Precooler Historic District ) is a Oviedo, Florida.
• The "'R . W . Estes Celery Company Precooler Historic District "'( also known as the Nelson & Company Precooler Historic District ) is a Oviedo, Florida.
• The engine inlet diffuser also has to slow the incoming air to subsonic speeds because if the air moved through the precooler and compressor at supersonic speeds, it would cause damage to them.
• The A2's engine, SCIMITAR, has precooler technology which is somewhat similar to SABRE, but does not have the rocket features, and is optimized for higher efficiency for atmospheric flight.
• The SABRE engine design aims to avoid this by using some of the liquid hydrogen fuel to cool helium in a closed-cycle precooler, which quickly reduces the temperature of the air at the inlet.
• The precooler adds mass and complexity to the system, and is the most aggressive and difficult part of the design, but the mass of this heat exchanger is an order of magnitude lower than has been achieved previously.
• In January 2011, REL submitted a proposal to the British government to request additional funding for the project and in April REL announced that they had secured $ 350 million of further funding contingent on a test of the engine's precooler technology being successful.
• The losses from carrying the added weight of systems shut down during the closed cycle mode ( namely the precooler and turbo-compressor ) as well as the added weight of Skylon's wings are offset by the gains in overall efficiency and the proposed flight plan.
• Below 5 times the speed of sound and 25 kilometres of altitude, which is 20 % of the speed and 20 % of the altitude needed to reach orbit, the cooled air from the precooler passes into a modified turbo-atmospheres into the combustion chambers of the main engines.
• REL intends ultimately to operate as a for-profit commercial enterprise, manufacturing Skylon vehicles for multiple international customers; these customers will operate their fleets directly, with support from REL . While REL intends to manufacture some components directly, such as the engine precooler, other components have been designed by partner companies and a consortium of various aerospace firms is expected to handle full production of Skylon.
