Aircraft Smoke Systems?

Question

How do they work? Is it unlimited?

Answer 1

True above, generally in the US we use corvus oil (used to coat the inside of concrete casting molds) injected into the exhaust.  The tank can be of whatever size you can fit.

Answer 2

All smoke systems work essentially in the same way: pumping a smoke fuel from a separate tank into the muffler. The smoke fuel, on contact with the hot exhaust gases and muffler walls, burns creating smoke.

With only an average of a 4 gallon tank it'll only last depending on how much oil you have in it and how long you fly for

Answer 3

Basically it works by injecting paraffin into the exhaust manifold.

Various dyes are used to create different smoke colours.

The system is limited by how much fluid can be carried (weight is limited depending on aircraft type and payload verses performance)

Answer 4

The Red Arrows inject diesel into the jet efflux from the engine.Dyes are used for the colours, and the tank that contains the diesel, I believe, is a converted aden cannon pod.
