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 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.

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. ;)

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.

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.

The EMP, or Electromagnetic pulse, is a rapid magnetic fluctuation which induces pulses of current in unshielded electronics. Natural sources of EMP include lightning, whereas artificial ones include a nuclear blast.
A nuclear blast generates an EMP via gamma radiation interacting with air molecules to create Compton electrons. These create a brief current and an associated electromagnetic pulse. This is especially hazardous with an exo-atmospheric nuclear blast outside the atmosphere, as the region affected by Compton electrons in such a manner becomes enormous and the electrons will rotate around the Earth's natural magnetic field lines, creating a vast pulse.
EMPs and NEMPs are extremely hazardous to unshielded electronics, causing rapid fluctuations in current, especially in long wires or antennae.

Yes, this might be something of an intellectual masturbation, but it's more fun than actually working. Hey-ho.
