Successful Demonstration and Verification of Ram-Jet Thrust in Supersonic Flight

An unequivocal demonstration of ram-jet thrust at supersonic speeds took place Wednesday, June 13, 1945, with the launching at Island Beach, New Jersey, of a Model 3 ram-jet, whose range about 11,000 yards was nearly double that of the same model launched cold. This was verified the following day by launching a second bird identical to the first, and the range this time was recorded as 14,000 yards. Both, the above birds burned CS2. Supporting evidence was accumulated by the launching of two additional models similar to the above except for the use of pentane and acetaldehyde fuels, respectively these latter units showed a 50 per cent increase over the range of the cold models.
