The fuel stores the chemical energy, released as it burns when ignited. To create the explosion, you need two key elements: a fuel source and an oxidising agent. Instead of the gases hitting a piston, they are forced directly out of a nozzle. In a rocket engine, the principle is similar – except for one key difference. The explosive energy contained within the burning fuel is thus converted to mechanical energy. This then turns a crankshaft leading to the wheels. In an internal combustion engine – the type used in cars – gas is ignited and expands in a chamber, forcing a piston down. It’s not rocket science (except, of course, it is). Igniting and controlling these immense explosions is the key to space travel, but how is this achieved?īefore we get into the mechanics of individual types of rocket engines, we need to familiarise ourselves with the basic physics involved. Three, two, one, liftoff! A spacecraft blasts from the launch pad, propelled by the massive thrust generated by its rockets.
