Abstract : This test and flight-evaluation report describes QT-33A aerial target smoke-generating systems used to assist airborne and ground observers to acquire the target visually. One system uses JP-4 from the aircraft's fuel supply. Another, with a 35-gallon supply tank, uses a mixture of petroleum white mineral oil and JP5. Both systems eject fluid through a nozzle into the engine exhaust area to produce a smoke trail. Piloted flight tests showed that the JP-4 system generates a usable smoke trail only at altitudes where the temperature is -20C or colder (about 18,000 feet and above). Ground and unmanned flight tests showed that the tank system, filled with five parts mineral oil and one part JP-5, generates usable smoke trails from ground level to at least 28,000 feet MSL. The report also describes and recommends a simplified aircraft tubing configuration usable with both systems. (Author)
