Project High Altitude Research Program (HARP) is directed toward the use of guns for scientific probing of the upper atmosphere. The attractive features of guns for this purpose are the basic economy of such a system and the high inherent accuracy of guns for placement at altitude as well as accuracy in ground impact. The basic liability for such an approach lies in the very high acceleration experienced by gun-launched payloads. The guns used in Project HARP vary in size from 5-inch and 7-inch extended guns on mobile mounts to transportable fixed 16-inch guns. Altitude performance varies from 20 pound, 5-inch projectiles reaching 240,000 feet to 185-pound, 16-inch projectiles reaching 590,000 feet. Single and multiple stage rockets launched from the 16-inch gun have very promising predicted performance and are under development. Scientific results to date are parimarily wind profiles measured by radar chaff, aluminized balloons and parachutes, and tri-methyl-aluminum trails, although a number of successful 250 MHz and 1750 MHz telemetry flights have been made. Sun sensors, magnetometers, and temperature sensors have been flown and an electron density sensor was fired in early June. Development of other active sensors is continuing. (Author)
Upper atmosphere winds measured by gun-launched projectiles( Book )

1 edition published in 1966 in English and held by 1 WorldCat member library worldwide

The High Altitude Research Project (HARP) uses gun-launched projectiles to probe the upper atmosphere. Under this project, 5-inch projectiles have reached 70 km, and 16-inch projectiles have attained an altitude of 143 km over Barbados, West Indies. The first experimental program for the 16-inch gun has been the production of luminous tri-methyl aluminum (TMA) trails for the measurement of winds above 90 km. In the period July 1964 to February 1966, 49 such nightime trails were photographed and 29 of these trails have been analyzed. During 42 of these flights, concurrent ionosonde records were taken and the locations of sporadic E layers have been determined for comparison with the wind profiles. The wind data analyzed showed little evidence for the Rosenberg rotating wind vector model, but on nine trails direction reversals occuring in less than 3 km of vertical displacement were observed. Layers of constant direction flow with thicknesses greater than 8 km were observed on 14 trails, and a maximum wind speed of 147 m/sec was measured. The six trails of the night of 20 - 21 September showed a rapid variation of N - S component of wind at fixed altitude with peak-to-peak amplitude of over 200 m/sec. Sine waves were fitted to wind components at fixed altitude with fair to good standard deviations. (Author)
