WebC-130 flare and chaffdispensers Flares burn at thousands of degrees Celsius, which is much hotter than the exhaust of a jet engine. IR missiles seek out the hotter flame, believing it to be an aircraft in afterburneror the beginning of the engine's exhaust source. Webas straw and chaff, in air stream, require knowledge of aerodynamic characteristics of all the particles involved. Furthermore, it was noted that a range of air velocities, for effective separation of the grain from MOG need to be estimated. As such, the terminal velocity (Vt) be used as an important aerodynamic characteristic of materials in
