Optimum Trajectories to Circular Synchronous Equatorial Orbit for Smaller-than-optimum Apogee Motors
Author: Omer F. Spurlock
Publisher:
ISBN:
Category : Calculus of variations
Languages : en
Pages : 36
Book Description
Analysis, procedure, and results are presented for maximizing payload capability for trajectories to circular synchronous equatorial orbit where thea pogee motor total impulse is much smaller than optimum. The trajectories begin at launch and are numerically integrated to insertion into the final orbit. Constraints on parking orbit perigee radius and duration are included. These trajectories, unlike conventional synchronous orbit trajectories, were found to require noncircular parking orbits and large amounts of inclination reduction before the apogee burn. The analysis and procedure were also applied to the conventional circular synchronous equatorial orbit problem where the burn and coast durations are optimum. Results are presented for the Applications Technology Satellite (ATS)-E missiod, which is an example of a problem where the apogee motor is small, and for the conventional case where the apogee motor is of optimum size.

Simulation Study of Three Instrument Displays to Assist in Airplane Thrust Management
Author: Milton D. McLaughlin
Publisher:
ISBN:
Category : Airplanes
Languages : en
Pages : 802
Book Description
Three displays were evaluated on a piloted simulator, each of which provided information which could be used in thrust management. The three displays were (1) rate of change of speed, (2) potential flight-path angle, and (3) potential rate of climb. Results are presented in the form of time histories, histograms, and pilot comments. The results include comparisons of flight-path and speed control and throttle activity with and without each display and pilot comments.
