Anotace:

Subject clarifies substantial relations and effects of force influence of flowing fluid on surface of airfoil, wing or complete airplane at subsonic or supersonic airspeeds. There are discussed elements of propeller, jet and rocket propulsion and necessary conditions for airplane stability and control subject. Further subject deals with basic tasks of airplane performance, motion of spacecraft in space and its re-entry to earth surface.
