Colonial slang of 'colour'.
"Behold, for I cannot spell color correctly!"
-Doesn't actually exist. There is no such faction or mindset as an 'evolutionist', which has so far not prevented the more literal-minded creationists from leaping on the title.
Evolutionist. -A fine example of poor English topped off with a platform to stand on.
A loss of lift over a lifting body, usually caused by separation of the flow from the upper surface of the lifting body/ aerofoil.
Common types of stall by flow separation include leading edge, trailing edge and thin aerofoil stalling.
The plan stalled, and fell wildly out of control.
The horseshoe vortex system is a simple vortex model for an aircraft or lifting body which fits a box-shaped vortex system out from the wing. This is made up of the wing vortex, trailing vortices (see trailing vortex
) and starting vortex. The latter is a vortex formed due to changes in the vorticity of the wing vortex, i.e due to changes in airspeed.
I can't honestly think of a good example for you. Sorry
The trailing vortex, also known, smewhat erroneously, as the 'wingtip vortex', is created due to the pressure differentials between the upper and lower sides of an aircraft wing. The resultant vorticity 'coils up' to form distinct trailin vortices, trailing from the wingtips. The assumption of perfect line-vortex systems from the wingtips is inherent in the horseshoe vortex
The trailing vortex was visible in the air.
A lens which focuses light rays from a source into parallel paths, thus focusing the image relayed at infinity. Highly useful in Head-Up-Display systems, for obvious reasons.
This will be the 2nd in my series of largely useless technical jargon, which will continue as it is more fun writing this than writing a report on the performance and aerodynamics of an MAV.
-For more amusing and less contrived definitions, look up my ones for France or Europe. They're OK.
A SCRamjet, or Supersonic Combustion Ramjet, is a propulsive device with no compressor stage or turbine. Like the ramjet, it compresses incoming air via shock formation and kinetic means as a result of it's own forward speed.
The key difference between a ramjet and scramjet is that the scramjet, as it's name suggests, may combust a fuel/ air mix at supersonic velocity, whereas a ramjet slows and compresses incoming air to subsonic velocity before combustion.
The scramjet is useful in the field of hypersonic propulsion systems.
The United States is experimenting with hypersonics for military means. Air-breathing scramjets are the usual source of propulsion.
