Convergent-divergent nozzle, the term “static pressure at the exit,” denoted as pe, refers to the pressure of the fluid at the exit section of the nozzle. A convergent-divergent nozzle is a type of nozzle used in supersonic and hypersonic flows to accelerate a fluid (often a gas) to high velocities. In this type of nozzle, […]

Velocity of the object or fluid flow is the speed at which the object is moving through the medium. In the context of supersonic flow, “u” represents the velocity of the object or flow relative to the medium, which can exceed the speed of sound. Specific heat ratio (𝛾) Specific gas constant (R) in J/kg*K

The Mach number, denoted as M, is a dimensionless quantity used to describe the speed of an object or fluid flow in relation to the speed of sound in the surrounding medium. Specifically, it’s commonly used to characterize supersonic and hypersonic flows, where the speed of the object or flow exceeds the local speed of

Airspeed at which an aircraft experiences the lowest amount of aerodynamic drag. This is a crucial concept in aviation because it represents the point at which an aircraft can achieve the most efficient use of its engine power for a given lift-to-drag ratio.\ Vmd: Velocity at minimum drag (speed at which the aircraft experiences minimum

In flight mechanics, the term “minimum thrust” refers to the lowest amount of thrust that an aircraft’s engines or propulsion system must generate in order to maintain a specific flight condition. This condition is usually associated with steady and level flight, where the forces acting on the aircraft are in balance. Tmin: This might refer

L’ represents the lift force per unit span, which is the aerodynamic force that is perpendicular to the fluid flow direction, acting on a unit length of the object. Lift is a critical aerodynamic force responsible for generating upward forces and supporting the weight of aircraft and other objects in flight. Static pressure at the
The “lift per unit span for a wedge,” denoted as L’, refers to the aerodynamic force generated per unit length of the wedge-shaped object in a fluid flow. This force is exerted perpendicular to the direction of the fluid flow and is a key component of the aerodynamic forces that affect the object’s behavior. Force
