| Applicatication Of the Rhumb Line Control Strategy To The Highly Spinning Dash Orbiter (2007) | |||||||||||||
Abstract | |||||||||||||
| The paper reveals the essential feature of the attitude control system for the demonstrator of atmospheric reentry system with hyperbolic velocity (DASH) and evaluates its fundamental performance. The spinning DASH orbiter is scheduled to be launched in January 2000 into a geo-stationary transfer orbit (GTO) by the first H-IIA rocket. It deorbits by burning of a solid propellant motor and releases a tiny reentry capsule, which will execute atmospheric flight. To ensure the planned decelerating direction, the attitude of the module is adjusted by rhumb line control technique prior to the ignition of the solid propellant deorbiting motor. The accuracy of the control will play a key role in the mission as it directly affects the range of the landing point dispersion. Although the maneuvering strategy itself cannot be considered special, a relatively high spinning rate of the module makes the problem absolutely different. The level of fluctuation in response time delay of the actuating sys... | |||||||||||||
