Dynamic Stability and Control Characteristics of a Ducted-Fan Model in Hovering Flight (open access)

Dynamic Stability and Control Characteristics of a Ducted-Fan Model in Hovering Flight

Report presenting the results of an experimental investigation of the dynamic stability and control of a simple ducted-fan model in hovering flight in order to provide basic information on the stability and control of jet vertically rising airplanes in hovering flight. The investigation primarily consisted of flight tests with the model hovering at altitude and near the ground.

Experimental Effects of Propulsive Jets and Afterbody Configurations on the Zero-Lift Drag of Bodies of Revolution at a Mach Number of 1.59 (open access)

Experimental Effects of Propulsive Jets and Afterbody Configurations on the Zero-Lift Drag of Bodies of Revolution at a Mach Number of 1.59

The present investigation was made at a free-stream Mach number of 1.59 to compare the afterbody drags to a series of conical boattailed models at zero angle of attack. Afterbody drags were obtained for both the power-off and the power-on conditions. Power-on drags were obtained as a function of afterbody fineness ratio, jet pressure ratio and divergence, and jet Mach number.

Experimental influence coefficients for the deflection of the wing of a full-scale, swept-wing bomber (open access)

Experimental influence coefficients for the deflection of the wing of a full-scale, swept-wing bomber

Report presenting the results of deflection tests on the wing of a full-scale, swept-wing jet bomber in the form of structural influence coefficients relating the deflection of a system of points on the wing and concentrated loads applied on the wing spars. The procedures for determining the coefficients are included.

The effects of wing-mounted external stores on the trim, buffet, and drag characteristics of a rocket-propelled model having a 45 degree sweptback wing (open access)

The effects of wing-mounted external stores on the trim, buffet, and drag characteristics of a rocket-propelled model having a 45 degree sweptback wing

Memorandum presenting a rocket-propelled model flown to determine the effects of four wing-mounted bomb-type external stores on the trim, buffet, and drag characteristics of a wing-fuselage configuration with a 45 degree sweptback wing. The model is compared with data from a similar model without stores. Results regarding trim, buffet, lift and stability, and drag are provided.
