To date, the REL Production Facility has inspected almost 18000 tubes and approximately one third of the total is ready for assembly into the Pre-cooler modules.
This month a large Heat Exchanger for the helium loop was delivered to REL’s test facility. This hardware will be tested at B9 in mid-2011.

Firecrest Engine Testing
As reported last month, Airborne Engineering and the University of Bristol conducted a number of shake-down tests of their experimental hybrid rocket engine, called Firecrest. The Firecrest engine burns high-density polythene fuel with nitrous oxide and can be fitted with either a conventional nozzle or an Expansion/Deflection (ED) Nozzle. It will be used in the Canary test rocket to discover the behaviour of ED nozzles in a high-speed air flow.
All of last month’s seven preliminary tests used a conventional conical nozzle. This month the team test fired an ED nozzle for the first time. Unfortunately, the experimental graphite nozzle suffered a failure a short time after ignition. Despite the failure, there are no risks to plans or schedule and a redesign of the nozzle is under way.

Latest Movie - Project Troy
The latest REL movie on Project TROY was completed this month. The Company has devised a Mars mission scenario where SKYLON is used as the launch vehicle to Earth orbit. The aim of the movie is demonstrate how a feasible, affordable, practical and safe mission to Mars can be achieved using SKYLON to enable a team of explorers to land at three sites and explore over 90% of the surface. This mission architecture also creates the infrastructure to support further missions. The Project TROY movie shows what a Mars mission would look like and how it would be constructed and performed.
