Description

Memorandum presenting a flight investigation to determine the effect of a propulsive jet on the zero-lift drag characteristics of two twin-exit boat-tailed bodies at transonic speeds. The two models had ratios of jet area to base area of 0.394 and 0.590 and covered a Mach number range of 0.8 to 1.15. A slight reduction in drag coefficients from power-off values are obtained during power-on flight for both models.
