Abstract: Двухконтурный турбореактивный двигатель с тепловым насосом содержит входное устройство, вентилятор, внутренний контур, внешний контур. Внутри внутреннего контура расположены компрессор среднего давления, теплообменник-испаритель, компрессор высокого давления, камера сгорания, турбины. Внутри внешнего контура расположены теплообменник-конденсатор, сужающееся сопло. Внутренний контур соединен с атмосферой через выхлопные патрубки, которые пересекают внешний контур. Теплообменник-испаритель и теплообменник-конденсатор закольцованы между собой через гидравлический насос, имеют общее рабочее тело - жидкость, переходящую в пар и обратно. Объем жидкости равен объему каналов теплообменника-испарителя, по которым течет вода, и объему трубопроводов, соединяющих теплообменники. Теплообменники позволяют понизить температуру воздуха на входе в компрессор среднего давления и одновременно повысить температуру воздуха перед соплом. Это обстоятельство позволяет повысить степень повышения давления воздуха в газотурбинном двигателе, сохранив при этом разницу температур газа на выходе из камеры сгорания и на входе в камеру сгорания, а также осуществить регенерацию теплоты во внешнем контуре, что в итоге позволяет повысить экономичность двигателя при сохранении его тяги. 3 з.п. ф-лы, 3 ил.
