Scramjet

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.

Supermanouevreability

The ability of an aircraft or aerial vehicle to maintain accurate pitch control in the post-stall regime of high-alpha flight.

Evident in:

-Eurofighter Typhoon.
-Su37.
-F22.
-Most Hollywood fighters. Hollywood clearly knows things the aerospace industry doesn't.

Ha. Let's see how many people bother looking *this* up. ;)

Cyrillic

An alphabetical system, highly phonetic in nature, used in many Eastern European and traditionally orthodox nations.

-Confused the living crap out of me when I visited Bulgaria.

Bulgarian use the cyrillic alphabet.

Collimating lens

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.

wanker

Slang.

1) One who masturbates to excess.
2) One who uses the word 'skillz' and takes it seriously.

"Stop saying skillz, you bloody wanker! Speak properly!"

Trailing vortex

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 model.

The trailing vortex was visible in the air.

Useless.

Aha! There goes another useless psychologist!
