THE INFRARED RADIANT INTENSITY OF SEVERAL SMALL PROPELLER-DRIVEN AIRCRAFT (U)
NAVAL ORDNANCE TEST STATION CHINA LAKE CALIF
A series of 10 different propeller-driven aircraft were measured by the Naval Ordnance Test Station to determine their infrared radiant intensities for various aspects. These measurements were sponsored by the Federal Aviation Agency to ascertain if sufficient radiation was emitted by commonly-encountered aircraft to offer a means of developing an infrared collision-warning device. The aircraft models selected for measurement were chosen by the Federal Aviation Agency as representative types of small civilian and commercial airplanes. They included both single and twin-engine aircraft. The measurements were made by means of a ground-based radiometer which recorded the infrared irradiance from various aircraft flying planned patterns above it. The radiation emitted by the aircraft was measured in the 2-3 micron wavelength band and the 3-6 micron wavelength band. Author
