Catapult launch TwinJet with Lambert Kolibri turbine

Electro jet TwinJet launch with Lambert T32 Kolibri turbine - 243.000 RPM full throttle and 99.000 on idle RPM - 1.66 kg thrust - approx 200-250 km/h - 380 ml kerosene fuel - flights 5-6 minutes - model weight 1.0 kgr - launch is at 75% of top RPM only for safety (turbine downthrust)

Very Nice - a question - is the launcher sself contained or do you run a long bungee cord across the ground - I could not see in the video - also if self contained do you have any details you can share ?? thanks

I use a part of a Graupner N°223 bungee, just to give it the initial launch speed. The vertical acceleration on the video is already fully on turbine power.

Do a search to "Lambert Turbinen"

Great launcher too! what is it?

[spiderjets]

The ramp is custom made from some scrap plywood, and the elastic pulling the plane is from Graupner for RC sailplanes. The foot pedal is operating a simple hook release mechanism.

Nicht schlecht!! Ich habe auch einen Twinjet von Multiplex, mit einer mini Turbine. Sie hat s.u.s 6,3k Schub!!!!!!!!!!!!!!! Eigenbau Turbine!

[spiderjets]

No need for such thrust. 1,66 kgr of power for a plane of 1,0 kg and an exhaust speed of 1550 km/h is more than enough. Mine is ballistic already, and a real show stopper.

Very Very Nice!

Very nice jet and I really like the turbine set up. Where can I find the Lambert T32 turbine? I would like to build one soon! Thanks.
