Effects of errors on decoupled control systems by Harold A Hamer( Book )

7 editions published in 1978 in English and held by 98 WorldCat member libraries worldwide

Various error sources in a decoupled control system are considered in connection with longitudinal control on a simulated externally blown jet-flap STOL aircraft. The system employed the throttle, horizontal tail, and flaps to decouple the forward velocity, pitch angle, and flight-path angle. The errors considered were: (1) imperfect knowledge of airplane aerodynamic and control characteristics; (2) imperfect measurements of airplane state variables; (3) change in flight conditions, and (4) lag in the airplane controls and in engine response. The effects of the various errors on the decoupling process were generally minor. Significant coupling in flight-path angle was caused by control lag during speed-command maneuvers. However, this coupling could be eliminated by including the control lag in the design of the decoupled system. Other error sources affected primarily the commanded response quantity

1 edition published in 2016 in English and held by 41 WorldCat member libraries worldwide

Mathematician and computer scientist Katherine G. Johnson was born on August 26, 1918 in White Sulphur Springs, West Virginia. She attended West Virginia State College where she met Dr. W.W. Schieffelin Claytor who created a special course in analytic geometry for her continued education. Johnson earned her B.S. degree in French and mathematics in 1937. She then worked as a high school mathematics teacher until 1953 when she became a research mathematician for the National Aeronautics and Space Administration (NASA). Johnson worked in the Flight Research Division before moving to the Spacecraft Controls Branch. In 1961, she calculated the trajectory of Alan Shepard’s Mercury Flight. In 1962, she verified the mathematics behind John Glenn’s orbit, and in 1969, she calculated the trajectory for the Apollo 11 flight. Johnson received NASA’s Lunar Spacecraft and Operation’s Group Achievement Award and the NASA Langley Research Center Special Achievement Award. Johnson retired from NASA in 1986

Fixed-angle translunar guidance procedures using onboard optical measurements by Harold A Hamer( Book )

2 editions published in 1971 in English and held by 29 WorldCat member libraries worldwide

Onboard procedures requiring only simple calculations have been developed for midcourse and approach guidance for translunar trajectories. For midcourse guidance the procedure relies solely on an optical range measurement. The approach-guidance procedure requires a star-to-body measurement and may require a range measurement, depending on the distance to the moon. For both procedures the velocity-correction vector is applied in a fixed inertial direction. In the approach-guidance procedure either one or two guidance maneuvers are applied, depending on the accuracy desired and tile distance to the moon. An error analysis showed that perilune radius can be controlled to a onesigma accuracy of about 30 km

An approach guidance method using a single onboard optical measurement by Harold A Hamer( Book )

4 editions published in 1970 in English and held by 12 WorldCat member libraries worldwide

An empirical method has been developed for onboard guidance within the sphere of influence of a celestial body. For guidance maneuvers made at a relatively large distance from the body, only one preselected measurement from a star to the body is required. Although the method is designed to control the magnitude of the periapsis radius (or entry angle), the periapsis position and velocity automatically remain close to the nominal values. For lunar approach, error analysis with an assumed one-sigma error of 10 seconds of arc in the optical angular measurements and a one-sigma velocity-cutoff error of 0.2 m/sec has shown that perilune radius can be controlled to a one-sigma accuracy of from 7 to 13 km, depending on the time the approach guidance is performed
