Wind Tunnel Tests of the Aerodynamic Characteristics of a 155 mm Artillery Shell
Abstract
The aerodynamic characteristics of a 1/3rd scale 155 mm artillery shell model were measured as a preliminary step in a program to assess the feasibility of using nose mounted controls on a spinning projectile to control its flight path and hence its point of impact. Tests were conducted for Reynolds numbers of 1.0 to 4.0 x 10 to the fifth power, incidences of zero to 20 deg, Mach numbers of 0.7 to 1.8, and roll rates of zero t 400 rev/s. Results indicate that the use of nose mounted controls to control the attitude an hence the flight path of a 155 mm shell is unlikely to be very effective within the subsonic and transonic Mach number range.
