Abstract : The purpose of the project was to design, develop, test, and furnish five (5) deiced, fast response, dual element total temperature sensors. Five (5) such sensors, REC Model 102CK2AY, were furnished to the USAF. The sensor design and development consisted of: (1) The design and development of a fast response, dual temperature sensing element. (2) The modification of the REC Model 102 deiced sensor housing to accept the dual element assembly and to increase the strut length to 4.5 inches. (3) The testing of the deiced, dual element total temperature sensor. The Model 102CK2AY total temperature sensor meets all of the requirements of specifications MIL-P-25726B and MIL-P-27723A, as applicable, and has a time constant of less than 0.3 seconds. The sensor is capable of accurately sensing temperatures when the sensor is subjected to a wind tunnel icing test at an indicated airspeed of 325 = 25 knots, temperature of -30 = 5C, and liquid water content of 1.25 = .25 grams per cubic meter.(Author)
