Report presenting an extensive collection of lift and hinge-moment characteristics of control surfaces up to a Mach number of 0.90 in a high-speed wind tunnel. A wide variety of control-surface profiles, plan forms, and aerodynamic balances are included. Results regarding elevator hinge moments and longitudinal control, aileron hinge moments and lateral control, control-surface characteristics, and transonic flutter are highlighted.

Memorandum presenting an investigation conducted to determine experimentally turbine-nozzle-blade and turbine-bucket temperatures in a turbojet engine and to correlate these temperatures with the gas temperatures. Data were obtained over the normal range of engine speeds and with two tail-pipe-nozzle areas. Results regarding basic data, turbine-nozzle-blade temperature distribution, turbine-bucket-temperature distribution, temperature distribution of gas at burner-outlet, turbine-bucket temperatures during starting, and relation of material and gas temperatures are provided.

Report presenting a method for applying the limited contraction ratio to obtain the maximum allowable blade thickness of a two-dimensional model of a supersonic-compressor rotor.
