hotol การใช้

• HOTOL's rear mounted engine gave the vehicle intrinsically poor in-flight stability.
• Previous versions of precoolers such as HOTOL put the hydrogen fuel directly through the precooler.
• Instead, as part of the HOTOL project, the RB545 engine was developed with more efficient cycle.
• As a Business Development Manager he ran infrastructure studies on launch systems ( BAe HOTOL, BAe Multirole Capsule.
• In 1989, after funding for HOTOL ceased, Bond and several others formed Reaction Engines Limited to continue research.
• Hotol was to have been a 50-to-60-passenger plane that would take off from conventional airports.
• In August 1984, BAe unveiled a public display of the HOTOL satellite launcher project and released details on its proposed operations.
• BAe's head of future business Peter Conchie stated that, if possible, HOTOL should become apart of the European space framework.
• At around the same time, the HOTOL tried to use precooled jet engine technology, but failed to show significant advantages over rocket technology.
• In the 1980s, he was one of the creators of the HOTOL spaceplane project, along with Dr . Bob Parkinson of British Aerospace.
• Alan Bond brought a precooled jet engine design he had invented to the HOTOL project, and this became the Rolls Royce RB545 rocket engine.
• In December 1984, a Hermes space vehicle had inadvertently generated support and interest amongst European Space Agency ( ESA ) members in the HOTOL project.
• Early attempts to fix this problem had ended up sacrificing much of HOTOL's payload potential, and contributed to the failure of the project.
• On the BBC Micro implementation, the messages displayed are " Support Hotol ", " Physics is fun " and " I love space ".
• Space plane designs may draw on the experience of " Hotol, " a pilot project of British Aerospace and Rolls-Royce a decade ago.
• There are several differences compared with HOTOL . Whereas HOTOL would have launched from a rocket sled, to save weight, Skylon uses a conventional retractable undercarriage.
• There are several differences compared with HOTOL . Whereas HOTOL would have launched from a rocket sled, to save weight, Skylon uses a conventional retractable undercarriage.
• The British Government partnered in 2015 with the ESA to promote a possibly commercial single-stage to orbit spaceplane concept called Alan Bond after HOTOL was canceled.
• In mid-1990, further British research and major reengineering to avoid deficiencies of the HOTOL design led to the far more promising Skylon design, with much greater payload.
• In November 1985, discussions between George Keyworth noted American interest in collaboration on developing hypersonic vehicles such as HOTOL, and that a prototype could be flying as early as 1990.
