Air Conditioning EXA Reloaded Expert Series Kit

The Klima EXA rocket model is powered by a D series rocket engine. Experimental model of EXA rocket is made of plastic mouldings. The EXA is 610 mm long and is lowered to the ground by a parachute. This set was originally released 10 years ago and after a long hiatus it is back. The model contains a special ejection chamber, which serves to protect the return device (parachute, ribbon) from the hot gases of the ejection engine. These go through a labyrinth in which they cool down and the temperature on the discharge side is reduced to an acceptable limit where the parachute is not damaged. It is therefore not necessary to use the ejector plug.

Sweep chamber

The model contains a special ejection chamber, which serves to protect the return device (parachute, ribbon) from hot gases of the ejection component of the engine. These go through a labyrinth in which they cool down and the temperature on the discharge side is reduced to an acceptable limit where the parachute is not damaged. It is therefore not necessary to use the ejector plug.

The difficulty of building a rocket

Estes level 4 rocket kits require a high degree of modeling work, from the actual building of the rocket to the painting. Assembly is very difficult. The parts are processed using unique wood and paper processing technologies. The result is a rocket that is an exceptional model. Construction can take several weeks. The assembled model must be painted - we recommend using acrylic spray paint.

Phases of flight

1. Engine ignition - the burner ignites the fuel mixture in the engine. The desired direction of flight is ensured by the guide rod of the launch pad on which the rocket is mounted.
2. Thrust and acceleration - the rocket is propelled by the reactive power of the rocket engine.
3. Burning out of the propellant mixture - once the propellant mixture burns out, the delay mixture begins to burn, producing a large amount of smoke. This is used to track the flight of the rocket. The fast-moving rocket is now beginning to slow down.
4. Top of flight and ejection - after the delay mixture burns out, the ejection mixture is ignited, which activates the rocket's reentry system.
5. The return system - is most often implemented by means of a parachute, ribbon, or so-called. heli-blade.
