METHOD FOR DETERMINING CHARACTERISTICS OF LONGITUDINAL CONTROLLABILITY AND STABILITY OF AIRPLANES

摘要

FIELD: experimental technologies of aerodynamics and static aero-resilience. ^ SUBSTANCE: method is based on using resiliently-dynamically similar models. Model is made overweight in several times and at given flow speed distribution of mass forces acting in direction of raising force is measured. After that, for each value of banking angle, independently from each other, values of deviation angles are measured for height and attack rudder. Simultaneously with that in all joints of suspension transverse forces active on model are measured, and also force of frontal resistance, acting on one of hinge joints. Then, aforementioned operations are repeated for altered distance from aforementioned hinged joint to center of weight of model, and characteristics of stability and controllability are determined. ^ EFFECT: increased precision of the experiment, wider range of determined parameters.
