The Lockheed F-94 Starfire was a first-generation jet powered all-weather day/night interceptor aircraft designed and produced by Lockheed Corporation. It was the first operational United States Air Force (USAF) fighter equipped with an afterburner as well as being the first jet-powered all-weather fighter to enter combat during the Korean War. The thermal efficiency is expressed mathematically as: where: ηth​ is the thermal efficiency, Tv​ is the thrust produced by the […]

Thermal efficiency is a measure of how well an engine or a system converts the heat energy from fuel into useful work. For aircraft like the Lockheed P-80 Shooting Star, thermal efficiency is a critical factor in evaluating the overall performance of the propulsion system. For the Lockheed P-80 Shooting Star, which was equipped with

The Lockheed P-38 Lightning was a World War II-era fighter aircraft. The thermal efficiency is a term more commonly associated with heat engines like gas turbines or internal combustion engines rather than aircraft as a whole. However, I can provide a general explanation. Thermal efficiency is a measure of how well an engine or system

The Rolls-Royce RB.162 is a lightweight British turbojet engine produced by Rolls-Royce Limited. Developed in the early 1960s, it was specially designed for use as a lift engine for VTOL aircraft but was also used in a later variant of the Hawker Siddeley Trident airliner as an auxiliary boost engine. A smaller related variant, the RB.181 remained a design project only, as did a turbofan version designated RB.175. The thermal efficiency is

The Rolls-Royce RB.145 was a British jet engine designed in the early-1960s by Rolls-Royce for use as a lightweight VTOL lift and cruise engine. Developed from the Rolls-Royce RB108 the RB.145 featured more accessories and a higher thrust rating. Six engines developed by MAN Turbo were fitted to the first prototype of the EWR VJ 101 experimental German fighter aircraft, achieving supersonic flight by July 1964. The thermal efficiency is expressed mathematically

The Rolls-Royce RB.401 was a British two-spool business jet engine which Rolls-Royce started to develop in the mid-1970s as a replacement for the Viper. RB.401-06 prototype engines were already being manufactured when a decision to develop the higher thrust RB.401-07 was taken. The thermal efficiency is expressed mathematically as: where: ηth​ is the thermal efficiency, Tv​ is the thrust produced by the engine, Vjet​ is the jet

The thermal efficiency of an aircraft like the Falcon 50 EX is typically discussed in terms of its propulsion system, specifically the engines. For the Falcon 50 EX, specific details about its thermal efficiency would depend on the engines installed. The Falcon 50 EX is equipped with three Honeywell TFE731-40 engines. The thermal efficiency is

The Dassault Falcon 5X is a business jet that was under development by Dassault Aviation. Unfortunately, the Falcon 5X program was terminated by Dassault Aviation due to various technical issues. Generally, the thermal efficiency of an aircraft is not directly calculated or specified for an entire aircraft like it is for an engine. Instead, thermal

The Rolls-Royce RB282 is a new series of twin-spool turbofan engines under development by Rolls-Royce. The thermal efficiency is expressed mathematically as: where: ηth​ is the thermal efficiency, Tv​ is the thrust produced by the engine, Vjet​ is the jet velocity, ​ṁf is the mass flow rate of fuel, hc​ is the specific enthalpy of the fuel.  

The Rolls-Royce RB.211 is a family of high-bypass turbofan engines that has been widely used in various commercial and military aircraft. The thermal efficiency of a turbofan engine is a measure of how effectively the engine converts the chemical energy in fuel into useful work, primarily in the form of thrust. The thermal efficiency is
