Flight Evaluation Of Various Phugoid Dynamics And 1 Th Values For The Landing Approach Task

Download or read book Flight Evaluation of Various Phugoid Dynamics and 1/Th Values for the Landing-approach Task written by Charles R. Chalk and published by . This book was released on 1966 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longitudinal handling qualities in the landing approach are studied. The T-33 variable stability and variable drag airplane was used in a flight program to evaluate various short period dynamics, phugoid dynamics, drag characteristics and elevator control authority levels. The first phase of the flight program was directed mainly at longitudinal short period dynamics, drag variation with angle of attack and elevator control authority. The second phase of the flight program was directed at phugoid dynamics, short period frequency, elevator control authority and drag characteristics. Drag variations with angle of attack, airspeed and elevator deflection were considered. Pilot ratings and comments are related to the airplane characteristics tests.
