Description / Abstract:
This information report presents a preliminary discussion of
liquid propellant gas generation (LPGG) systems. A LPGG system, as
used herein, is defined as a system which stores a liquid
propellant and, on command, discharges and converts the liquid
propellant to a gas. The LPGG system can interface with a
gas-to-mechanical energy conversion device to make up an auxiliary
power system. Figure 1 shows a block diagram of LPGG system
components which include a propellant tank, propellant expulsion
system, propellant control and a decomposition (or combustion)
chamber.
The purpose of this report is to provide general information on
the variety of components and system arrangements which can be
considered in LPGG design, summarize advantages and disadvantages
of various approaches and provide basic sizing methods suitable for
initial tradeoff purposes.
