EXHAUST PIPE FOR THE TJ20A TURBOJET ENGINE
The manufacturer of the TJ20A engine recommends to use an exhaust pipe with the engine, to
protect the model against damage caused by the high temperature of the engine output nozzle.
The exhaust pipe must be designed in accordance with the following figure.
Recommended material for the exhaust pipe: refractory or stainless-steel, thickness 0.2 mm.
The L2 length is specified when ordering.
If L2 is higher than 500 mm, we recommend a double-sheathed design.
A suitable inlet cone must be installed at the exhaust pipe inlet.
The outer part of the engine nozzle must extend 40 mm into the inlet cone at the turbine side!
