Effects of Symmetric and Asymmetric Thrust Reversal on the Aerodynamic Characteristics of a Model of a Twin-engine Airplane
Investigation of the dynamic lateral stability and control characteristics of a model of a fighter airplane without a horizontal tail and equipped with either single or twin vertical tails
Investigation of the Aerodynamic Characteristics of a Model Wing-Propeller Combination and of the Wing and Propeller Separately at Angles of Attack up to 90 Degrees
This report presents the results of an investigation conducted in the Langley 300 mph 7- by 10-foot wind tunnel for the purpose of determining the aerodynamic characteristics of a model wing-propeller combination, and of the wing and propeller separately at angles of attack up to 90 degrees. The tests covered thrust coefficients corresponding to free-stream velocities from zero forward speed to the normal range of cruising speeds. The results indicate that increasing the thrust coefficient increases the angle of attack for maximum lift and greatly diminishes the usual reduction in lift above the angle of attack for maximum lift
Wind-tunnel Investigation of the Effects of Geometric Dihedral on the Aerodynamic Characteristics in Pitch and Sideslip of an Unswept- and a 45 Degree Sweptback-wing-fuselage Combination at High Subsonic Speeds
