The maximum lift-to-drag coefficient, often denoted as (CL/CD)max, is a key performance metric used to assess the aerodynamic efficiency of an aircraft. It represents the highest achievable ratio of the lift coefficient (CL) to the drag coefficient (CD) for a given aircraft configuration, operating condition, and flight regime.  (CL/CD)max is the maximum lift-to-drag ratio e […]

The mass of air refers to the total amount of air present in a given volume or a specific space. It represents the combined mass of all the molecules and particles that make up the air within that particular region.  𝜌 represents the density of the gas p is the pressure of the gas R

Enthalpy per unit mass, denoted as “h,” is a thermodynamic property that represents the total heat content of a substance per unit mass. It quantifies the total energy contained within the substance, including both its internal energy and the energy associated with its pressure-volume work.  h is enthalpy per unit mass cp is the specific

Internal energy per unit mass, denoted as “e” is a thermodynamic property that represents the amount of total energy contained within a substance per unit mass. It quantifies the microscopic energy associated with the motion, position, and interactions of the molecules and atoms that make up the substance.  e is the internal energy per unit

The term “constant pressure” refers to a condition or situation where the pressure of a system remains unchanged or does not vary with respect to time. Constant pressure is often used to describe specific types of processes, particularly in relation to the specific heat capacities of gases.   cp is the specific heat capacity at constant

Internal energy is typically used in thermodynamics and refers to the total energy contained within a substance due to the motion and interactions of its molecules and atoms. In the context of a gas, such as air, internal energy is related to the kinetic energy of the gas molecules and their potential energy due to

Enthalpy refers to the total heat content of the air present within that room. It takes into account both the sensible heat and latent heat of the air. Sensible heat is the heat associated with the temperature of the air, while latent heat is the heat associated with phase changes, such as evaporation or condensation. 

Wing loading (W/S) is the weight carried by an aircraft’s wing per unit area of the wing. It is a measure of how much weight the wing needs to support relative to the total wing area.  W: Aircraft Weight is the total weight of the aircraft, including its payload, fuel, and structure, and S: Wing

In aerodynamics, span loading refers to the distribution of lift along the span of an aircraft’s wing. It is a measure of how lift is distributed from one wingtip to the other. The span loading profile is crucial in determining the aerodynamic behavior and performance of the aircraft.  W: Aircraft Weight is the total weight

The “induced angle of attack” (𝛼i) is an aerodynamic concept that describes the additional angle of attack experienced by an aircraft’s wing due to the generation of lift. It is caused by the wing’s vortices, which are swirling masses of air that form at the wingtips when the aircraft generates lift.  𝛼i is the induced
