The aircraft design process is the engineering design process by which aircraft are designed.
Brake specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power.
The density of air ρ (Greek: rho) (air density) is the mass per unit volume of Earth's atmosphere.
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.
In statistical mechanics, entropy is an extensive property of a thermodynamic system.
In thermodynamics, a heat engine is a system that converts heat or thermal energy—and chemical energy—to mechanical energy, which can then be used to do mechanical work.
Horsepower (hp) is a unit of measurement of power (the rate at which work is done).
The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.
Konstantin Eduardovich Tsiolkovsky (a; Konstanty Ciołkowski; 19 September 1935) was a Russian and Soviet rocket scientist and pioneer of the astronautic theory of ethnic Polish descent.
Mechanical efficiency measures the effectiveness of a machine in transforming the energy and power that is input to the device into an output force and movement.
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy.
In Newtonian mechanics, linear momentum, translational momentum, or simply momentum (pl. momenta) is the product of the mass and velocity of an object.
A propellant or propellent is a chemical substance used in the production of energy or pressurized gas that is subsequently used to create movement of a fluid or to generate propulsion of a vehicle, projectile, or other object.
In thermodynamics, a reversible process is a process whose direction can be "reversed" by inducing infinitesimal changes to some property of the system via its surroundings, with no increase in entropy.
Rolls-Royce Holdings plc is a British multinational public limited company incorporated in February 2011 that owns Rolls-Royce, a business established in 1904 which today designs, manufactures and distributes power systems for aviation and other industries.
Specific impulse (usually abbreviated Isp) is a measure of how effectively a rocket uses propellant or jet engine uses fuel.
Thermodynamic temperature is the absolute measure of temperature and is one of the principal parameters of thermodynamics.
Thermodynamics is the branch of physics concerned with heat and temperature and their relation to energy and work.
Thrust-specific fuel consumption (TSFC) is the fuel efficiency of an engine design with respect to thrust output.
The Tsiolkovsky rocket equation, classical rocket equation, or ideal rocket equation, describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and thereby move due to the conservation of momentum.
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion.
A turboprop engine is a turbine engine that drives an aircraft propeller.
There are a broad range of metrics that denote the relative capabilities of various vehicles.
