Unreasonable Rocket Update

Paul Breed has a new update on his quest to build a nano-satellite launch vehicle.

Paul first started looking into this back in 2012, even going as far as entering the Space Frontier Foundation, NewSpace business plan competition. Recently he has resurrected his plan and idea with a newfound approach. Paul is no stranger to rockets and space, having entered in Level 1 of the Northrop Grumman Lunar Lander Challenge with his VTVL rocket “Blue Ball” and level 2 with “Silver Ball”.

Unreasonable Rockets current approach for a nano-satellite launcher uses the OTRAG example, where common propulsion modules (tanks and engines) are strapped together to form a larger rocket and staged as necessary along its flight path. This common propulsion module approach was first tried in the 1970s, although never making an orbital flight, and is also the approach being used by Interorbital Systems for their N-5 rocket.

Work has been carried out on carbon fibre tanks and it is now that a mass ratio (wet mass to dry mass) of 15 has been achieved with the current set up. Work now continues on an extended version of the tank for testing and motor design, that will be 3D printed. An artist rendering of the proposed rocket is shown below.

This promises to be a very exciting project and one that will deliver.
