Abstract
Abstract A pump or generator is connected to the drive shaft of a vehicle to induce a braking effect not provided by the twin shaft gas turbine powering the vehicle. The output of the pump or generator is stored and used to drive the compressor of the turbine in place of fuel during coasting and/or idling of the vehicle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
In an automotive vehicle, a twin shaft type gas turbine having a combustor, a compressor and an output shaft connectable to a drive shaft of the vehicle via a clutch; energy producing means for producing a storable energy; first drive means for providing temporary drive connection between said drive shaft of said vehicle and said energy producing means to produce an engine braking effect to induce deceleration of said vehicle; storage means connected to said energy producing means for receiving and storing said storable energy; second drive means connected to said compressor for maintaining the rotational speed of said compressor above a predetermined level upon being supplied with said storable energy stored in said storage means; and control means for selectively causing said first drive means to provide said temporary drive connection between said drive shaft and said energy producing means, supplying said second drive means with said storable energy stored in said storage means and cutting the supply of fuel to the combustor of said turbine.
Claim 2
Dependent Claim
167 words
In an automotive vehicle, a twin shaft type gas turbine having a combustor, a compressor and an output shaft connectable to a drive shaft of the vehicle via a clutch; energy producing means for producing a storable energy; first drive means for providing temporary drive connection between said drive shaft of said vehicle and said energy producing means to produce an engine braking effect to induce deceleration of said vehicle; storage means connected to said energy producing means for receiving and storing said storable energy; second drive means connected to said compressor for maintaining the rotational speed of said compressor above a predetermined level upon being supplied with said storable energy stored in said storage means; and control means for selectively causing said first drive means to provide said temporary drive connection between said drive shaft and said energy producing means, supplying said second drive means with said storable energy stored in said storage means and cutting the supply of fuel to the combustor of said turbine.
Claim 3
Dependent Claim
170 words
In an automotive vehicle, a twin shaft type gas turbine having a combustor, a compressor and an output shaft connectable to a drive shaft of the vehicle via a clutch, a hydraulic pump for pressurizing hydraulic fluid; first drive means for providing temporary drive connection between said drive shaft of said vehicle and said pump to produce an engine braking effect to induce deceleration, said first drive means being disabled when the rotational speed of said output shaft is above a predetermined level; reservoir means connected to said pump for storing pressurized hydraulic fluid from said pump therein; a hydraulic motor in drive connection with said compressor for driving said compressor to maintain the rotational speed of said compressor above a predetermined level upon being supplied with said pressurized hydraulic fluid; and control means for selectively causing said first drive means to provide said drive connection, supplying said hydraulic motor with pressurized hydraulic fluid from said reservoir means and cutting the supply of fuel to the combustor of said turbine.

In an automotive vehicle, a twin shaft type gas turbine having a combustor, a compressor and an output shaft connectable to a drive shaft of the vehicle via a clutch; electric current generating means for producing an electric current; first drive means for providing temporary drive connection between said drive shaft and said electric current generating means, said first drive means being disabled when the rotational speed of said output shaft is above predetermined level; electric storage means connected to said electric current generating means for receiving and storing electric current; second drive means in drive connection with said compressor for driving said compressor and maintaining the rotational speed of said compressor above a predetermined level upon being supplied with electric current from said electric storage means; and control means for selectively causing said first drive means to provide said temporary drive connection, for supplying electric current to said second drive means and cutting the supply of fuel to said combustor.
Claim 6
Dependent Claim
161 words
In an automotive vehicle, a twin shaft type gas turbine having a combustor, a compressor and an output shaft connectable to a drive shaft of the vehicle via a clutch; electric current generating means for producing an electric current; first drive means for providing temporary drive connection between said drive shaft and said electric current generating means, said first drive means being disabled when the rotational speed of said output shaft is above predetermined level; electric storage means connected to said electric current generating means for receiving and storing electric current; second drive means in drive connection with said compressor for driving said compressor and maintaining the rotational speed of said compressor above a predetermined level upon being supplied with electric current from said electric storage means; and control means for selectively causing said first drive means to provide said temporary drive connection, for supplying electric current to said second drive means and cutting the supply of fuel to said combustor.
Claim 7
Dependent Claim
133 words
In a method of operating a twin shaft type gas turbine for an automotive vehicle, said turbine having a combustor, a compressor and an output shaft connectable to a drive shaft of said vehicle via a clutch, the steps of: connecting means for producing a storable energy to said drive shaft of said vehicle via first drive means to induce an engine braking effect; storing said storable energy in energy storage means; disabling said first drive means when the rotational speed of said output shaft is above a predetermined level; and cutting the supply of fuel to said combustor and supplying said stored energy to second drive means in drive connection with said compressor to maintain the rotational speed of said compressor above a predetermined level, during coasting and idling of said vehicle.
