A method has been developed which makes possible the determination of the time to make a horizontal turn of any number of degrees, and also the control deflections necessary to make the turn. Accelerations encountered during the maneuver are easily obtained from the calculations which are used in obtaining the maneuvering time.
The method worked out is based on the six fundamental stability equations. The major assumptions are angle of bank [...], and no sideslip during turn i.e. V = 0. Only the use of simple wind tunnel data is necessary.
Several cases are worked out for different bank assumptions for a twin engine attack bomber. The bank assumption which gives the most reasonable control deflections and accelerations during the maneuver is one which produced a helix angle of 0.090 and maximum bank of 75°. For this particular bank assumption calculations were carried out for sea level and 15,000 ft. altitude.
Calculations were also carried through for sea level and 15,000 ft. for a modified single engine airplane of same weight and horsepower as the twin engine one, using the bank assumption which gave [...] max. of 75°.
A method is presented for the direct calculation of the stability derivative, M[...], from wind tunnel data.
