The papers mentioned below deals with Bull's work in the late 60's and early 70's: G.V. Bull and C.H. Murphy Review of the Hiogh Altitude Research Program (HARP) Paper given in the conference "The Fluid Dynamics Aspects of Ballistics" AGARD Conference Proceedings No. 10, 5-8 Sept. 1966 NASA is considering the use of a gun of about 18" diameter to study hypersonic flight (15 km/sec). This gun would fire a projectile horizontally through a covered range 1000 to 2000 ft. in length. This range could have any test gas of interest e.g. air, CO2.
