| description | This disclosure pertains to a jet propulsion power plant comprising a gas turbine engine having a first exhaust nozzle whose noise level is kept low by a relatively low pressure/area ratio at the nozzle, and having a plurality of second exhaust nozzles whose noise level is kept low by a pressure/area ratio of the individual nozzles which is sufficiently high to cause the peak of the noise spectrum to be of ultrasonic frequency. |
