Rocket Clutch

I had previously proposed designs that would catch the falling rocket stages “Catcher in the Fly” 

I thought about my old ideas and came up with a new design that catches the rocket while it is falling and safely land it vertically on the desired location. The idea is to use three turbojet packs that carry giant rubber clutches. 

The falling rocket stage would be initially slowed down using parachutes. Then, the jet packs would fly up and catch the rocket while adjusting their downward speed to match with the rocket’s. Afterwards, the jetpacks would approach the rocket closer until they grasp the casing with giant rubber clutches. Once engaged with the rocket, the jetpacks would increase their thrust to slow down the rocket. Finally, the afterburners would be fired until the rocket safely lands on the ground.

Each jetpack would be composed of 3 turbojet engines, a fuel tank, rubber clutches and landing legs. Turbojets are preferred over turbofan engines due to their lower weight and volume. Lower weight improves the agility of the jetpack. Smaller volume reduces the effect of lateral winds. Precise positioning will be achieved by thrust vectoring the jet engines. Finally, afterburners will allow boost of thrust when needed.

Once the design succeeds in catching the first stage of a rocket, it can be enhanced to catch the second stage as well. The mobility of the catcher system negates the need for a sea landing platform. Also, can adapt to the unplanned changes on the falling trajectory.
