The coefficient of lift (CL) is a dimensionless quantity used in aerodynamics to characterize the amount of lift generated by an aerodynamic object, such as an airfoil or wing, relative to the fluid flow around it.  CL: Lift coefficient e: Oswald’s efficiency factor AR: Aspect ratio CD,o: zero lift drag coefficient 

The zero-lift drag coefficient (CD,o) is a fundamental aerodynamic parameter that represents the drag coefficient of an aircraft when it is producing zero lift. In other words, it is the drag experienced by the aircraft when its lift coefficient (CL) is zero, which occurs when the aircraft is flying in straight and level flight without

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
