Abstract
Abstract A system for providing electrical energy to a missile and the like. The system including a turbine driven by a gas supply on board the missile. The turbine driving a generator thereby eliminating batteries and other electrical power sources heretofore used on missiles. The generator includes spring biased magnetic vanes forming the turbine rotor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A system for providing electrical energy to a missile and the like, the system comprising: a gas source adapted tor receipt on board the missile; a gas regulator connected to the gas source via a gas line; an integrated turbine driven generator having a generator housing, the housing having field coils mounted thereon, the housing also having a gas inlet connected to the gas line and a gas outlet, a turbine rotor received in the housing and having spring bias magnetic vanes slidable mounted therein and forming a positive displacement vane motor, the vanes rotating the rotor by gas expansion and the magnetic field set up therein cuts the field coils for providing an induced electrical current; and a power regulator connected to the field coils for regulating the amount of power to the missile's electrical system.
Claim 2
Independent Claim
137 words
A system for providing electrical energy to a missile and the like, the system comprising: a gas source adapted tor receipt on board the missile; a gas regulator connected to the gas source via a gas line; an integrated turbine driven generator having a generator housing, the housing having field coils mounted thereon, the housing also having a gas inlet connected to the gas line and a gas outlet, a turbine rotor received in the housing and having spring bias magnetic vanes slidable mounted therein and forming a positive displacement vane motor, the vanes rotating the rotor by gas expansion and the magnetic field set up therein cuts the field coils for providing an induced electrical current; and a power regulator connected to the field coils for regulating the amount of power to the missile's electrical system.
Claim 3
Dependent Claim
57 words
The system as described in claim 1 further including a control system for monitoring the power generated by the turbine driven generator, the control system connected to an electrical control valve, the valve connected to the gas regulator for controlling an increase or decrease of the gas thereby increasing and decreasing the speed of the turbine rotor.
Claim 4
Dependent Claim
24 words
The system as described in claim 1 wherein the gas source is a pressurized gas bottle charged by a gas generator in the bottle.
Claim 5
Dependent Claim
35 words
The system as described in claim 1 wherein the gas source is a pressurized gas bottle charged by a common gas chamber, the gas discharged from the chamber to the bottle via a one-way valve.
