Results are presented of a test program designed to study the capture coefficient of a liquid-helium- and liquid-neoncooled cryoplate exposed to a Mach 3 low density air stream. Capture coefficients are given for both a flat plate and an 80-deg half-angle conical plate placed normal and at an angle of attack to the air stream for the cases with and without a scaled fairing in front of the plates. Also presented are the effects on the shock structure in front of the plate when the plate is cooled to 4.2 K. Author
