Wind tunnel tests have been made to investigate the influence of the jets from several different nozzles on the pressure distribution on adjacent wing panels with supercritical profiles. In Part I, an existing unswept wing ...

In a single-axis gyro a rotation about the input axis forces the spin axis to rotate about the output axis. The true input axis is oscillating about its nominal position and the gyro sees a varying component of the angular ...

A method is given for calculating the temperature of a surface wetted either by a pure liquid, such as water, or by a mixture, such as alcohol and water. The method is applied to the problem of protecting; by alcohol, ...

Calculations by an integral method assuming small cross-flow, and by a finite-difference method assuming the flow to be quasi-conical, are compared with measurements made available by Hummel (Technical University, Brunswick) ...

For twin tandem units the wheel loading conditions which arise when aircraft are turned on the ground may be critical for the landing gear. To estimate the magnitude of these loads, cornering tests were made on a small ...

Optimal landing transition manoeuvres are studied for jet-lift VTOL aircraft in which the range of engine-tilt is sufficient to allow approach angles up to 20 degrees. The optimal use of incidence, thrust vector angle and ...
