Filed:

Jun 22, 1981

Appl. No.:

6/275727

Inventors:

Leo R. Kiley - Whitehall MI

Assignee:

Teledyne Industries, Inc. - Los Angeles CA

International Classification:

C09K 330
B01F 306

US Classification:

252305

Abstract:

A black smoke generator is provided for generating a smoke screen for use on military vehicles, installations and the like. The black smoke generator is a self-sustaining unit and comprises a compressor having an outlet, a turbine having an inlet and a burner assembly operatively connected between the compressor outlet and the turbine inlet. The burner assembly has a housing which defines a combustion chamber while fuel is supplied to the combustion chamber at a rate which produces an excessively rich fuel/air mixture in the combustion chamber. Upon ignition of the fuel/air mixture in the combustion chamber, black smoke is exhausted through the turbine which simultaneously drives the compressor. A method for generating black smoke is also disclosed.

Abstract:

A black smoke generator is provided for generating a smoke screen for use on military vehicles, installations and the like. In one form of the invention, the black smoke generator is a self-contained and self-sustaining unit and comprises a compressor having an air intake and a compressed air outlet and a turbine having an inlet and an exhaust outlet. A shaft is drivingly connected between the turbine and the compressor so that gases expanding through the turbine expander rotatably drive the shaft which in turn rotatably drives the compressor. A burner assembly having a housing which defines a combustion chamber is interposed between the compressor outlet and the turbine inlet while a source of fuel is connected to the combustion chamber and feeds fuel to the combustion chamber at a rate which produces an excessively rich fuel/air mixture in the combustion chamber. Upon ignition of the fuel/air mixture, black smoke is exhausted through the turbine which simultaneously drives the compressor. In a modified form of the invention, the smoke generator is adapted for use with an engine turbocharging system and includes a burner housing defining a combustion chamber.
