Claim 3

An apparatus as described in claim 1 wherein said charging means comprises: a. source of combustible gas, b. means for predetermining the amount of combustible gas to be introduced into said chamber, and c. means for introducing said predetermined amount of gas into said chamber.

Claim 4

An apparatus as described in claim 2 wherein said means for predetermining the amount of combustible gas introduced into said chamber comprises: a metering system which includes: a. control means, b. at least one valve normally closed for communicating said combustible gas, c. means for actuating said valve upon responsive to said control means, and d. means for regulating the duration said valve is actuated by said valve actuating means for a predetermined period of time.

Claim 5

An apparatus as described in claim 3 wherein said control gas introducing means and said regulations means comprises: a. a control gas source, b. a first control gas valve normally closed adapted for momentary manual opening for communicating said control gas, c. storage means coupled to said first control valve for storing a predetermined volume of control gas upon opening of said valve, and d. a discharge orifice coupled to said storage means opposite said first valve for discharging said volume of control gas to the atmosphere at a predetermined rate, and wherein said valve actuating means is coupled between said first valve and said storage means.

Claim 7

An apparatus as described in claim 5 wherein said applying means comprises:

Claim 8

a. means for selectively coupling said heating means and said current generating means.

Claim 9

a. means for selectively coupling said heating means and said current generating means.

Claim 10

The launch simulator of claim 1 wherein the igniting means comprises: a. a trigger for generating a signal as an indication of the initiation of a simulated launch, and b. an electronic circuit for processing the trigger signal and igniting the gas.

Claim 11

The simulator of claim 7 wherein the electronic circuit in the igniting means comprises: a. a filter section for generating a filtered signal in response to said trigger signal, b. a delay section for generating a delay signal in response to said filtered signal, c. a current generation section for generating current in response to said delay signal, and d. ignition means within said combustion chamber driven by said current.

Claim 12

A simulator as described in claims 7 or 8 wherein said means for introducing a combustible mixture into said chamber comprises: a. a source of control gas, b. a regulator having an output said regulator coupled to said source for outputting regulated control gas, c. at least one first valve having an input and an output said input coupled to said output of said regulator, d. at least one second valve having an input and an output said input coupled to said output of said regulator, e. means for actuating said first valve adapted for manual actuation, f. means for actuating said second valve having an input coupled to said output of said first valve said means adapted for actuation upon application of control gas pressure at said input, g. a source of combustible mixture, h. at least one mixture valve having an output coupled to said combustion chamber and an input coupled to said combustible mixture source, and i. a means for actuating said mixture valve having an input coupled to said output of said second valve said means adapted for actuation upon application of control gas pressure at said input.

Claim 13

A simulator as described in claim 9 wherein said introducing means further comprises: a. a delay tank having an input and an output for storing a predetermined volume of control gas, said input coupled to the output of said first valve and the input of said second valve actuating means, and b. a discharge orifice coupled to the output of said tank for discharging said control gas at a predetermined rate.

Claim 14

A simulator as described in claim 10 wherein said introducing means further comprises: a. a pressure actuable switch coupled to said output of said second valve, and b. a display means activated by said switch for indicating the actuation of said mixture actuation valve means.

Claim 15

The launch simulator of claim 1 wherein the end cap removably attached to the front end of the chamber contains a smoke producing agent which is actuated by the ignition of the gas.
