Rocket Propulsion and Guidance

2019
The technology of how a rocket moves, how it knows its orientation and how it controls the orientation are the subjects of this chapter. We will then take a slight diversion to consider the application of that control to the fine art of docking a spacecraft.

Principles of Rocket Propulsion

Journal of the Royal Aeronautical Society, 1933
A great deal of interest has recently been taken in the subject of rocket propulsion, undoubtedly in the main due to the rather extravagant hopes, raised by Professor Goddard (I) in 1919, that a projectile might actually be sent into interplanetary space.

Propulsive Efficiency of Rockets

1962
Publisher Summary This chapter examines the meaning and properties of rocket propulsive efficiency, for both constant and variable exhaust speed. Propulsive efficiency can be defined as a point function, that is, it depends on the instantaneous operating conditions.

Rocket Propulsion With Nuclear Power

ARS Journal, 1960
The nuclear reheat scheme for rocket propulsion using hydrogen propellant is briefly described, and then a scheme using a closed-cycle regenerative gas turbine working between the reactor as a heat source and the liquid hydrogen as a heat sink is treated in detail. The turbine, an AK unit, is filled with high-pressure helium.

Evolution of Energy for Jet and Rocket Propulsion

Aircraft Engineering and Aerospace Technology, 1946
Specific Heat of Gases THE chemical reaction having been accomplished and the energy of fuel released, we can follow its further transformation. It can be assumed that in the first stage this energy is absorbed and stored in the surrounding gaseous medium composed mainly of combustion products. The mechanism of the absorption and preservation of energy

Rocket Propulsion Cost Modeling

1989
The advent of the Strategic Defense Initiative has focused a great deal of attention on the United States capability to place large masses in orbit. Both the likely sizes and the numbers of satellites that may be required for SDI strongly suggest the need for a new generation of launch vehicles with low cost a priority requirement.

Nuclear rocket propulsion principle

Acta Astronautica, 1994
Abstract A high specific impulse, high thrust nuclear rocket propulsion principle is presented for discussion. The fission fuel retention problem is solved dynamically by a pulsed operation through a fast growing chain reaction.

The Rocket Propulsion Establishment, Westcott

The Journal of the Royal Aeronautical Society, 1966
In the first issue of the Journal for 1966, the Centenary Year of the Royal Aeronautical Society, an account of the history of the Rocket Propulsion Establishment, no matter how brief, may appear to some as an unwarrantable intrusion. It is in this year, 1966, that the Establishment will complete only its second decade of existence, but it may claim to

The History of Solid Rocket Propulsion and Aerojet

35th Joint Propulsion Conference and Exhibit, 1999
Abstract : Much of the early history of rocket propulsion has not been the subject of organized historical documentation, and with the passage of time, and proliferation of organizational changes, the prospects for developing a clear picture of past events and fading. These papers, and the book, upon which it is based, attempt to rectify this situation
