Inlet velocity of wind tunnel Calculator

The velocity of a wind tunnel refers to the speed of the airflow within the tunnel. Wind tunnels are specialized facilities used in aerodynamics and fluid dynamics research to study the behavior of air and other fluids around objects, such as aircraft, vehicles, buildings, and various engineering structures.  V1 is the inlet velocity V2 is

High propeller efficiency calculator

In flight mechanics, “high propeller efficiency” refers to a condition where the aircraft’s propeller operates with minimal losses and converts a significant portion of the engine’s power into useful thrust. Propeller efficiency is a crucial factor in aircraft performance as it directly affects fuel consumption, range, and overall effectiveness of the propulsion system. ηp= (2/1+Vj/V

Rate of change of momentum of the stream calculator

Thrust generated by a jet engine. According to Newton’s second law of motion, the force acting on an object is equal to the change in its momentum per unit time1 T=m*(Vj-V infinite) T = Thrust generated by the jet engine or propulsion system (force in Newtons or pounds-force) m = Mass flow rate of air
