This soon leads to the shock stall, causing a rapid increase in drag. Small, low-altitude general aviation planes typically have aspect ratios of six or seven airliners of 12 or more and high-performance sailplanes of 30 or more.Īt speeds above the critical Mach number, the airflow begins to become transonic, with local airflow in some places causing small sonic shock waves to form. This is best achieved with a high aspect ratio, and high-performance types often have this kind of wing.īut other considerations such as light weight, structural stiffness, manoeuvrability, ground handling and so on often benefit from a shorter span and, consequently a less efficient wing. It is therefore desirable for a wing to have the least area compatible with the desired lift characteristics.

The drag of a wing consists of two components: the induced drag, which is related to the production of lift, and the profile drag, largely due to skin friction which is contributed to by the whole wing area. A higher aspect ratio gives a higher lift/drag ratio and so is more efficient. The aerodynamic efficiency of a wing is described by its lift/drag ratio, with a wing giving high lift for little drag being the most efficient.
They are related by the aspect ratio, which is the ratio of the span, measured from tip to tip, to the average chord, measured from leading edge to trailing edge. The span and area of a wing are both important to the lift characteristics. Wing design A Spitfire built in 1945 shows off its straight elliptical wing Pure jets such as the turbojet and ramjet are inefficient at subsonic speeds and not often used. At higher subsonic speeds and at high altitudes, such as attained by most airliners, the turbojet or turbofan becomes necessary. Sometimes it is enclosed in the form of a ducted fan. The propeller is one of the most efficient sources of thrust available and is common on subsonic aeroplanes and airships. At high subsonic speeds, compressibility effects begin to appear.

She escaped to Earth and joined the Teen Titans.Starfire also appeared as one of the Teen Titans in the animated series in 2003.Subsonic flight is characterised aerodynamically by incompressible flow, where dynamic pressure changes due to motion through the air cause the air to flow away from areas of high dynamic pressure to areas of lower dynamic pressure, leaving the static pressure and density of the surrounding air constant. As Princess Koriand'r, she was experimented on by the Psions and developed the ability to fire bolts of energy.

She was one of the Eternal Champions of the Sornaii, raised as a slave of the Mygorg and as an adult broke free of slavery and started a resistance movement against the tyrannical King Sookarooth.The third Starfire appeared first in 1980 in DC Comics Presents. He later was known as Red Star, and joined the Teen Titans.The second Starfire appeared in her own comic in 1976. This first Starfire was a boy named Leonid Kovar who was exposed to an unknown energy when an alien spacecraft exploded when he and his father, a Soviet archaeologist, were exploring it. Not the ice cream thing!Another Version:The first Starfire appeared in 1963 in Teen Titans Comics.
The F-94C was a derivative of the old F-80 Shooting Star one of the first USAF jet fighters in production and sometime called by the alternate monicker of Jet Star. Most Lockheed planes had names with astornomical origins (Constellation, for example).
#Whats subsonic speed code#
One Verison:Among other things, possibly not the meaning you want, the Starfire was the code name for the Lockheed F-94C subsonic jet fighter, the Starfighter was the much faster F-l04 sometimes these are confused.
