Airbus suggested a propelled platform with its own set of wheels placed beneath the aeroplane's fuselage could help boost its acceleration before detaching just before take-off.
Hell, why not just use a conveyor belt - we all know it works!!!

Ah yes the Me163 Komet idea. Not sure how comfortable it would be to have an airliner landing on a skid though.

The trolley used by the 163 (and a similar idea used on the protype Arado 234 jet bomber) was not propelled by its own motor. It was a freewheeling trolley (or dolly).





The problems with any jetisonable undercart system are

a) what type of landing system will the aircraft use?

b) how will the aircraft be handled on the ground at its destination and how will it take off from that destination to return to its base?

Seems like the Airbus boffins have been twiddling their thumbs and wondering what to do since the A380 entered service. It's a cr@ppy idea really, isn't it? Does anyone really think that this will become reality within the next 38 years? Perhaps they popped down the local gliding club and saw how they do it with a cable and pulley!

Aren't they supposed to be working on the A350?

It's a non-story.

Here's my suggestion for a rapid undercarriageless take off -

The ZELL system is more impressive - no problems with landing either!

Don't open the duty frees until AFTER take off.

That's a crap BBC story.

The design has landing gear and the 'trolley' is more like a carrier-catapult system.

It's more a catapult system as opposed to a traditional "dolly" system.

Not exactly a brand spanking new idea either - the Wright Brothers used a system like this back in 1903.



Also, during WW2 Avro looked at something similar to assist heavilly laden bombers on take off. The Manchester/Lancaster was stressed for catapult take offs.

What's the largest aircraft that is / can be launched using a catapault? The biggest I can think of is the Hawkeye / Greyhound.

What about the Vigilante? They were awesome. It was one Airfix kit that I actually took some time over making when I was a nipper. Also the A-3 Skywarrior.

yes I saw a Vigilante in Arizona and it was huge! I'll dig out a close up picture later of the weapon release system when I get home.
