MULTISTAGE ROCKET FLIGHT SIMULATION

Human tolerance to multistage rocket acceleration curves.

I N T H E course of its flight, the occupants of a passenger-carrying rocket are subjected to accelerations differing substantially from that normally experienced. T, he use of a human centri.fuge capable of high peak acceleration and rate of change of acceleration allows us to duplicate sufficiently closely the acceleration curves of a rocket and to determine their effect on human beings in ad...

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...

One Dimensional Internal Ballistics Simulation of Solid Rocket Motor

An internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. In this model a 1-D unsteady Euler equation with source terms is considered. The flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. The governing equations in the combustion chamber are solved numerically by using the Steg...

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...
