Chase and published by . This book was released on 1968 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: A moving base pilot-in-the-loop simulator study was conducted to evaluate the effectiveness of direct lift control systems in improving the mission effectiveness of two types of aircraft. The missions considered were in-flight refueling, terrain following, and landing. The aircraft considered were the C-5A heavy cargo plane and the F-104 fighter-bomber. (Author).

This book was released on 1970 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current fighter aircraft have shown undesirable properties of dynamic maneuverability in the transonic region. A direct lift control system was designed to decrease pitch rate overshoot, eliminate normal acceleration reversal, and speed lift build up. The system used leading edge slats as the direct lift device due to the availability of transonic flight test data from a McDonnell-Douglas project. The slats had significant steady state benefits, as well as providing a suitable direct lift surface. The closed loop system was designed around a fly-by-wire primary flight control system, and used a linear blend of pitch rate and pilot acceleration feedback. This permitted investigation of handling qualities criteria in the manner of the newly proposed criterion. Digital computer solution provided extensive root locus analysis to determine stability and set optimum gains. The results were verified by a three-degree-of-freedom analog simulation. The problem was evaluated at five flight conditions covering a wide range of dynamic pressures. It was found that direct lift control gave significant transient improvement in load factor build up, reduced pitch rate overshoot, and permitted precise tracking capability in the transonic region.

Available in PDF, EPUB and Kindle. Book excerpt: A DLC (Direct Lift Control) system was designed for the F-111A to investigate the handling qualities such a system would produce on a variable sweep-wing aircraft. Flaps, symmetrically operating spoilers, and the differential elevator were adapted to respond to the pilot's normal longitudinal column movements with the intent of applying lift forces in the desired direction of flight without pitching the aircraft. The closed-loop controller consists of fixed-gain normal acceleration, pitch angle, and pitch rate feedbacks to the servos. The fixed gains were selected by use of a digital optimization program based on Kalman's Linear State Regulator Theory. The controller was then tested with a piloted analog computer simulation based on the short period approximation to the longitudinal equations of motion. Approach and landing, in-flight refueling, and transsonic flight were investigated; the latter two at more than one wingsweep. It was found that with DLC more precise changes in altitude or rate of climb can be made without significant increase in normal acceleration. In addition, rates of climb or descent up to 2000 feet per minute from level trim condition can be made with less than plus or minus one-half degree change in pitch angle. Crossover was eliminated.

Available in PDF, EPUB and Kindle. Book excerpt: Direct lift control (DLC) is a system which produces lift forces in the direction the pilot desires to move the airplane without significant pitching moment. DLC enhances precision longitudinal maneuvering capability by providing a change in altitude or rate of climb without a change in pitch attitude and without the initial acceleration reversal, delay in lift build-up, and excessive pitch rate overshoot associated with conventional elevator control. Operation of DLC in approach and landing is discussed. (Author).
