From Summary: "A flight test has been conducted to determine the longitudinal stability and control characteristics of a 0.125-scale model of the McDonnell F-101A airplane for the Mach number range between 0.82 and 1.84. The variation of lift-curve slope with Mach number was gradual with a maximum value of 0.107 occurring at a Mach number of 0.95. The minimum drag coefficient (including base and internal drag) has a value of 0.020 at a Mach number of 0.87. The drag rise begins at a Mach number of 0.90, and at Mach number of 1.10 the minimum drag is 0.070. Above this Mach number there is a gradual increase in minimum drag coefficient to a value of 0.074 when the Mach number is 1.83."

Memorandum presenting a wind-tunnel investigation of a high-wing airplane with an aspect ratio 6.75 wing with approximately 36 degrees of sweepback in order to determine the lift effectiveness obtainable with trailing-edge blowing flaps in combination with leading-edge slats. Close to theoretical flap effectiveness was obtained with blowing flaps deflected 45, 55, and 65 degrees at low angles of attack. Results regarding the wind tunnel, take-off performance, landing performance, and comparisons with flight data are provided.

Report presenting a wind-tunnel investigation of a high-wing airplane with an aspect ratio 6.75 wing with approximately 36 degrees of sweepback to determine the lift effectiveness obtainable with trailing-edge blowing flaps in combination with leading-edge slats. Flap effectiveness and stability were maintained to high angles of attack by control of leading-edge flow separation with slats. An analysis of the take-off performance, landing performance, and comparisons with flight data are provided.

Relative velocities of the flame in a carbon monoxide - air mixture containing either added heavy water or light water were measured in a glass tube. Throughout the range of carbon monoxide - air composition, the flame containing added light water had a faster speed than the flame containing heavy water.

Memorandum presenting results of an experimental investigation of the flow near the nose of plane and axially symmetric bodies in the presence of detached shock waves, which are compared with predictions of theory. The location of the detached shock wave was determined from schileren photographs for a variety of nose shapes over a range of free-stream Mach numbers from 1.8 to 2.9. Results regarding schileren photographs, shock-location parameter, effect of b/T on shock form, effect of body form on shock form, effect of angle of attack on shock form and location, pressure distributions, drag coefficients, and nose inlets are provided.

Report presenting an investigation of the transonic flutter characteristics of a cantilevered, aspect-ratio-4, 45 degree sweptback, untapered wing with three different pylon-mounted external-store configurations. An additional study was created during the investigation to find a store configuration with a substantially higher flutter speed than what was obtained with the other two stores. Results regarding general comments, the investigation of store types A and B, node-line survey, and the investigation of store type C are provided.

Report presenting a study of the first stage performance characteristics of the two-stage turbine from the J73 turbojet engine. The reduced-chord first-stage turbine operated at a peak brake internal efficiency of over 91 percent at a stage overall pressure ratio of 1.4 and at 90 percent of the design equivalent speed. The unit exhibited high efficiency over a wide range of operating variables.

Report presenting an investigation of a reduced-chord multistage turbine at design speed and various turbine-inlet pressures from 12 to 40 inches of mercury absolute. At each inlet pressure, the turbine was operated over a range of overall turbine total-pressure ratios; turbine-inlet temperature was maintained at 700 degrees R. The results indicated that no appreciable effect on turbine overall performance was observed over the range of turbine-inlet total pressures investigated.

Report presenting flight tests to study the effect on aiming error in azimuth of a change in the rudder-pedal-force characteristics of a conventional fighter airplane equipped with an illuminated fixed gunsight. The effect of the modification on the mean azimuth tracking errors was insignificant, but pilots noted that the modified rudder made it tiring to fly the airplane for any length of time.
