Abstract
LIFT AND CONTROL CHARACTERISTICS OF A CIRCULAR AIRPLANE EMPLOYING THE COANDA EFFECT WILL BE INVESTIGATED EXPERIMENTALLY AND ANALYTICALLY. A SCALE MODEL WILL BE CONSTRUCTED, INSTRUMENTED AND TESTED FOR LIFT FORCES, VELOCITY AND PRESSURE PROFILES. A FINITE DIFFERENCE METHOD OF ANALYSIS OF THE FLOW OVER THE BODY WILL BE DEVELOPED, USING A PARABOLIC MARCHING TECHNIQUE AND A MIXING LENGTH MODEL WITH EMPIRICAL CORRECTIONS.
