Test TT-38k Radial Decoupler in flight over Kerbing. Less than 4k meters, greater than 1210m/s

[rude0411]

Contract I'm working on wants me to fire the decouplers between 0-4000 meters altitude, while flying 1210-1870 m/s.

I've tried staying low and burning liquid fuel, can't get that fast that low. I've tried going really fast off the bat... Can't get that fast before I hit 4k meters. I've tried getting it on re-entry... Seems to hit a terminal velocity below 1210 m/s way before I get back under 4k meters. I'm stumped. Please help.

My suggestion is to try to complete it with a rocketplane.  

 

Also is particularly important to check the parameters of this kind of contracts,  some combinations of heigh and speed are way more trouble than the contract is worth.

Assuming you have probes, put a probe on top of a flea, put two fleas on each side, nose cones on them and nothing else.  Maybe launch almost horizontal also

It's possible with any of high-thrust rockets, RAPIERs, or Whiplashes, but you'll need thermally resistant parts on the front to make it happen, or else you'll explode.

Something like this should do it. Get up to about 5,000m at Mach 2, nose down, light the blue touch paper on the hammers and back home in time for tea and medals.
