Aerospace Instrument-Making Annotation << Back METHODOLOGY OF IDENTIFICATION THRUST AND FUEL EXPENDITURE CHARACTERISTICS OF AN AIRCRAFT ENJINE S.V. Nikolaev, A.P. Tupitsyn The article is devoted to the identification of thrust and specific fuel consumption of a turbojet engine as part of an aircraft. A technique is shown to determine the traction and flow characteristics of a turbojet engine in fixed operating modes. The efficiency of the technique is demonstrated by a concrete example from the practice of testing an aircraft. A feature of the methodology is the procedure for calculating the traction and consumption characteristics of the engine through the non-inductive coefficient of excess thrust and the reduced instantaneous fuel consumption obtained in horizontal rectilinear acceleration modes. Keywords: aircraft, aircraft testing, turbojet engine, thrust identification, turbojet engine characteristics. DOI: 10.25791/aviakosmos.5.2023.1340 Pp. 36-45.
