MAIN ENGINE BRAKING DEVICE UTILIZING EXPLOSION PRESSURE AND EFFECTIVE PRESSURE ULTIMATE UTILIZING TYPE TURBINE MECHANISM TO BE MAIN ENGINE

Japanese Patent JP3735832

B2

PROBLEM TO BE SOLVED: To improve operation efficiency of a main engine by constituting device and mechanism so as to provide a disc wheel of a disc wheel type turbine mechanism main body and a disc wheel of a main engine braking device on a common shaft and to lead explosion pressure of the turbine mechanism main body to a nozzle port of the main engine braking device.
SOLUTION: A turbine engine main body has a first stage and a second stage constituted by being provided with each impulse disc wheel 4, 5, pressure loss preventing plates 25, 26 which are very close to both of left and right ends of the disc wheels 4, 5 and main body barrels 6, 7 storing these plates 25, 26. In each stage, reaction stationary blades opposed to each impulse disc wheel 4, 5 are further formed on internal surfaces of main barrels 6, 7. The turbine engine main body constituted in this way and a main engine braking device constituted by storing disc wheels 15 for air brake within the barrels 6, 7 are disposed on a main shaft 1 to be a common shaft. Explosion pressure generated by an operation of the turbine engine main body is discharged from a discharge port, this pressure is led to a nozzle port of the main engine braking device as necessary and a disc wheel 14 for air brake is revolved.
