(54) СПОСОБ РЕГУЛИРОВАНИЯ ГАЗОТУРБИННОГО ДВИГАТЕЛЯ(54) METHOD FOR REGULATING A GAS TURBINE ENGINE
1one
Изобретение относитс к газотурбостроению и в частности может найти применение при регулировании автотракторного газотурбинного двигател .The invention relates to a gas turbine and in particular can be used in the regulation of an autotractor gas turbine engine.
Известен способ регулировани газотурбинного двигател путем перераспределени расходов первичного и вторичного воздуха в камере сгорани и поддержани за счет такого перераспределени заданного соотношени топлива и воздуха в зоне горени 1.There is a method of controlling a gas turbine engine by redistributing the primary and secondary air flow rates in the combustion chamber and maintaining, through this redistribution, a predetermined ratio of fuel and air in the combustion zone 1.
Однако реализаци такого способа св зана с усложнением конструкции камеры сгорани вследствие размещени в ней механических средств регулирующих расходы. Это увеличивает вес и габариты камеры. Кроме того, такое регулирование не позвол ет повысить экономичность двигател .However, the implementation of such a method is associated with the complexity of the design of the combustion chamber due to the placement of mechanical means for controlling the costs therein. This increases the weight and size of the camera. In addition, such regulation does not improve the efficiency of the engine.
Известен также способ регулировани газовоздушного двигател путем изменени расхода топлива в зоне горени камеры сгорани 2.There is also known a method for regulating a gas-air engine by varying the fuel consumption in the combustion zone of the combustion chamber 2.
Недостатком такого способа вл етс относительно низка приемистость двигател и забросы температуры газа перед турбиной на режиме разгона.The disadvantage of this method is the relatively low engine throttle response and gas temperature surges ahead of the turbine during acceleration.
Целью изобретени вл етс улучшение приемистости и повышение экономичности двигател на режиме разгона.The aim of the invention is to improve the injectivity and increase the efficiency of the engine during acceleration.
Указанна цель достигаетс тем, что одновременно с изменением расхода топлива в сторону увеличени подают в зону горени воздух от постороннего источника с поддержанием стехиометрического соотношени смеси топливо-воздух.This goal is achieved by the fact that simultaneously with a change in fuel consumption in the direction of increase, air is supplied to the combustion zone from an external source while maintaining the stoichiometric ratio of the fuel-air mixture.
При разгоне автотракторного газотурбинного двигател с частотой враш,ени турбокомпрессора, равной 56-60% от номинальной до частоты вращени , равной 94-96°/о от номинальной одновременно с увеличением подачи топлива подают в зону горени воздух от постороннего источника 15 с давлением на 0,01-0,02 МПа, превышающим давление в зоне горени и в количестве до 5% от его расхода на данном режиме, причем подачу воздуха производ т с поддержанием стехиометрического соотношени смеси топливо-воздух. После разгона подачу воздуха отключают.During acceleration of an autotractor gas turbine engine with a rotational frequency of a turbocharger equal to 56-60% from nominal to a rotational speed equal to 94-96 ° / o from nominal, simultaneously with the increase in fuel supply air is supplied to the combustion zone from 0 , 01-0.02 MPa, exceeding the pressure in the combustion zone and in the amount of up to 5% of its consumption in this mode, the air being supplied with maintaining the stoichiometric ratio of the fuel-air mixture. After acceleration, the air supply is turned off.
Такое осуществление регулировани газотурбинного двигател позвол ет на 8-12Уо повысить его экономичность и на 5, улучшить приемистость двигател . 34This implementation of the regulation of the gas turbine engine makes it possible to increase its economy by 8-12 ° C and by 5, to improve engine throttle response. 34
