Abstract
Abstract A gas turbine engine of a gas-coupled type suited for driving a vehicle has auxiliary devices such as an air conditioning compressor and a generator driven by the gas generator turbine. To facilitate acceleration of the gas generator and thus acceleration of the vehicle from idling or low power condition, these auxiliary devices are temporarily declutched from the engine during such acceleration.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A gas turbine engine comprising, in combination, a compressor, turbine means connected to drive the compressor and connectable to drive an external load, combustion apparatus connected in flow circuit between the compressor and the turbine means, means for supplying fuel to the combustion apparatus including a settable fuel control, and power-consuming auxiliaries driven by the turbine means in conjunction with the compressor, characterized by the combination therewith of a disengageable clutch means between the said auxiliaries and the turbine means providing the sole power input from the engine to the said auxiliaries, and control Means responsive to resetting of the fuel control to accelerate the turbine means effective to disengage the clutch temporarily so that the said auxiliaries are normally driven by the turbine means and are not driven while the clutch is disengaged.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
139 words
A gas turbine engine comprising, in combination, a compressor, turbine means connected to drive the compressor and connectable to drive an external load, combustion apparatus connected in flow circuit between the compressor and the turbine means, means for supplying fuel to the combustion apparatus including a settable fuel control, and power-consuming auxiliaries driven by the turbine means in conjunction with the compressor, characterized by the combination therewith of a disengageable clutch means between the said auxiliaries and the turbine means providing the sole power input from the engine to the said auxiliaries, and control means responsive to resetting of the fuel control to accelerate the turbine means effective to disengage the clutch during acceleration of the turbine means so that the said auxiliaries are normally driven by the turbine means and are not driven while the clutch is disengaged.
Claim 4
Dependent Claim
139 words
A gas turbine engine comprising, in combination, a compressor, turbine means connected to drive the compressor and connectable to drive an external load, combustion apparatus connected in flow circuit between the compressor and the turbine means, means for supplying fuel to the combustion apparatus including a settable fuel control, and power-consuming auxiliaries driven by the turbine means in conjunction with the compressor, characterized by the combination therewith of a disengageable clutch means between the said auxiliaries and the turbine means providing the sole power input from the engine to the said auxiliaries, and control means responsive to resetting of the fuel control to accelerate the turbine means effective to disengage the clutch during acceleration of the turbine means so that the said auxiliaries are normally driven by the turbine means and are not driven while the clutch is disengaged.
Claim 5
Dependent Claim
147 words
A gas turbine engine comprising, in combination, a compressor, first turbine means connected to drive the compressor, second turbine means connectable to drive an external load, combustion apparatus connected in flow circuit between the compressor and the turbine means, means for supplying fuel to the combustion apparatus including a settable fuel control, and power-consuming auxiliaries driven by the first turbine means in conjunction with the compressor, characterized by the combination therewith of a disengageable clutch means between the said auxiliaries and the first turbine means providing the sole power input from the engine to the said auxiliaries, and control means responsive to resetting of the fuel control to accelerate the first turbine means effective to disengage the clutch temporarily during acceleration of the first turbine means so that the said auxiliaries are normally driven by the turbine means and are not driven while the clutch is disengaged.
