BEATING HEAT PROBLEMS IN SUPERSONIC AIRCRAFT.—Methods of tackling the “heat barrier,” one of the major problems in the development of supersonic aircraft, were outlined in a recent report of the Society of British Aircraft Constructors. This is an artist’s impression of a large supersonic altitude test chamber which is being used to test cooling systems for supersonic airliners. Measuring 45ft long and 15ft wide, this test chamber can impose air temperatures and pressures found at heights up to 19 miles and at speeds of more than 2000 miles an hour on full-scale sections of aircraft fuselages in which complete air conditioning systems are developed.
