Flight Path Angle Steering with Lambert Guidance Reference

In this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. Generally the Lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. Because of uncertainties and undesired factors, the nominal position and velocity obtained by Lambert technique need to be followed in actual flight. ...

Flight Trajectory Path Planning

The paper describes an application of the A* algorithm for flight path planning for airplanes with defined motion dynamics operating in a continuous three-dimensional space constrained by existing physical obstacles. The presented A* algorithm modification provides significant acceleration (reduction of the state space) of the path planning process. The described algorithm is able to find a pat...

Animal studies of the subgravity state during rocket flight.

I N T H E I R D I S C U S S I O N of man under gravity free conditions, Gauer and Haber G were the first to suggest that subgravity might lead to interesting physiological effects. They did not anticipate direct disturbances of respiration and of the circulation. However, they thought that the conflict between normal visual observations and the changed impulses from the labyrinth and propriocep...

Parametric Diagnostics of Flight Control and Propulsion for Rocket Ascent

This paper describes a case study of model-based diagnostics system development for a space launch vehicle application. The diagnostics algorithms described in the paper can work with on-board or telemetry flight data. The key innovation is in designing a distributed diagnostics system that directly uses parametric data, such as sensors data. The computations are partitioned between the subsyst...
