The turbojet is an airbreathing jet engine which is typically used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet which includes inlet guide vanes, a compressor, a combustion chamber, and a turbine. The compressed air from the compressor is heated by burning fuel in the combustion chamber and then allowed to expand through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Two engineers, Frank Whittle in the United Kingdom and Hans von Ohain in Germany, developed the concept independently into practical engines during the late 1930s.

टर्बोजेट इंजन रॉकेट सिद्धांत पर कार्य करने वाला एक जेट इंजन है। इसमें एक नोदक चंचु के साथ गैस टर्बाइन लगी होती है। यह आमतौर पर तीव्र गति वाले विमानों मे उपयोग किया जाता है।
