EFFECT OF FOREBODY MODIFICATIONS ON THE AERODYNAMIC CHARACTERISTICS OF A SIMULATED AIRCRAFT STORE AT MACH NUMBERS FROM ).%) TO +.+&.
Abstract
An exploratory investigation was made of the effects of various forebody modifications on the logitudinal aerodynamic characteristics of a simulated low-drag aircraft store. Results were obtained at Mach numbers from 0.50 to 1.17 and angles of attack up to about 21 degrees. Specifically, the effects of progressively sliding a cylindrical sleeve forward over the store forebody, eliminating the store forebody for various sleeve projections, and of disk spoilers on the forbody were explored. The results show that the static stability characteristics of the store were improved by modifications which induced flow separation at some position on the store forebody. The extent of the Mach number and angle-of-attack ranges where improvements occurred was a function of both the modification and store center-of-gravity position (Which may shift with changes in the forebody).
