In aerodynamics, compression lift refers to the increased pressure under an aircraft that uses shock waves generated by its own supersonic flight to generate lift. This can lead to dramatic improvements in lift for supersonic / hypersonic aircraft.
In subsonic aerodynamics, the theory of lift is based upon the forces generated on a body and a moving gas (air) in which it is immersed. At airspeeds below about 260 kn (480 km/h; 130 m/s; 300 mph), air can be considered incompressible in regards to an aircraft, in that, at a fixed altitude , its density remains nearly constant while its ...
John Roncz was born to Peter John Roncz and his wife Catherine, nee Scheibelhut, of South Bend, Indiana, [2] who were married in June 1946. [3] Known as P. John Roncz, his father was a co-founder of Maron Products Inc, an engineering company specialising in metal stampings, mainly for the automotive industry.
An elliptical planform is the most efficient aerodynamic shape for an untwisted wing, leading to the lowest amount of induced drag. The semi-elliptical planform was skewed so that the centre of pressure, which occurs near the quarter- chord position at all but the highest speeds, was close to the main spar, preventing the wings from twisting.
Simulation of an airplane using Open VOGEL, an open source framework for aerodynamic simulations based in the UVLM. The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level.
Beverley Strahan Shenstone MASc, HonFRAes, FAIAA, AFIAS, FCAISI, HonOSTIV (10 June 1906 – 9 November 1979) was a Canadian aerodynamicist often credited with developing the aerodynamics of the Supermarine Spitfire elliptical wing.
The KF airfoil was designed by Richard Kline and Floyd Fogleman. Aircraft wing showing the KFm4 Step. In the early 1960s, Richard Kline wanted to make a paper airplane that could handle strong winds, climb high, level off by itself and then enter a long downwards glide.
Also, an aerodynamic force is imposed by the relative vertical positions of the fuselage and the wings, creating a roll-in leverage if the fuselage is above the wings, as in a low wing configuration; or roll-out if below, as in a high-wing configuration. A propeller rotating under power will influence the airflow passing it.
