ホイト・シュナイダ・プロペラに関する一考察 : (二次元準静的状態とし翼素運動径路のわん曲を考慮せる場合)

抄録

Study on Voith-Schneider-Propeller is made much complicated by several factors even in two-dimensional treatment. When the chord length is small, however, the propeller may be regarded as composed of blades, each individually moving along a trochoid relative to uniform flow (quasi-steady state, interference disregarded), with suitable correction for advance speed. The author tried to make some account on the action of the propeller as two-dimensional under above principle, taking into consideration the curvature of blade path relative to the uniform flow, as well as the azimuthal location of the control point, and here is given some numerical examples. Also an application to cyclo-gyro aircraft is referred to. It is known that for air transportation purpose, the direction of blade rotation must be chosen in conformity with what sort of airfoil is used.
