Before explanation the present invention, earlier existing turboaxle motor is done one and briefly introduce, and can not be applicable to that to it means of transportation such as automobile, train analyze.
As shown in Figure 1, for having the structure diagram of turboaxle motor now.Comprise the gas compressor 1, the firing chamber 2 that is positioned at the casing middle part that are arranged in the casing, be positioned at the driving turbine 3 that 2 right sides, firing chamber and gas compressor 1 are rotationally connected by turbine shaft 5, being rotationally connected in this specification is meant the connection that both can rotate synchronously.Drive the right side of turbine 3, be provided with the power turbine 4 (being also referred to as " free turbine ") that is used for output power and uses, this power turbine 4 is rotationally connected with line shaft 10, and line shaft 10 is isolated with turbine shaft 5, and both are discrete two sections.The air-flow that utilizes the firing chamber to produce drives free turbine output shaft power.
From top structure, because gas compressor 1 assembles on the same turbine shaft 5 with driving turbine 3, then the rotating speed of gas compressor equates with the rotating speed that drives turbine 3, according to the Brayton circulation, has following formula:
Wherein, γ
pBe pressure ratio, k is a gas constant, is about 1.421, and η is a mechanical efficiency.
As can be seen from the above equation, γ
pValue is big, and then the η value is also big.
γ
pIncrease along with the increase that drives secondary speed (being the gas compressor rotating speed).
When idling, γ
pVery low, so η is also very low, oil consumption very when causing low speed.
When idling, η is very low, when quickening, the mechanical force that produces is also little, thereby acceleration performance is poor, though by strengthening oil spout certain improvement can be arranged, but can cause high temperature, and the turboaxle motor of existing said structure is when quickening, the power that gas compressor needs becomes the biquadratic growth with its rotating speed.
Compressor power W
Press=a * n
4
Wherein a is a constant.
During idling, if rotating speed promotes, then the power of gas compressor needs becomes biquadratic to increase, and acceleration performance is just poorer like this.
If the pressure ratio γ during with idling
pDesign greatlyyer, η can become greatly like this, and fuel consumption can descend during low speed, but along with the increase of rotating speed, γ
pCan be excessive, W
PressAlso can be excessive, fuel also may exceed its firing pressure scope, causes rotating speed to be difficult to rise.
When existing above-mentioned turboaxle motor is applied to the operating mode of less parking deceleration in the runnings such as aircraft, steamer, the disadvantages affect that its acceleration performance is poor, the low speed oil consumption is big is little, and be in for automobile, train etc. need often to stop, for the means of transportation of decelerating mode, then can bring remarkable influence, inapplicable.
