Reaction Engines has posted its latest monthly update for December 2011:

Annual General Meeting (AGM): The REL AGM took place on 7th Dec 2011 at the company’s headquarters in Oxfordshire. After the meeting the shareholders were taken on a tour of the new production facility at the Culham Science Centre. REL received positive feedback on the progress made.

7th Appleton Space Conference: Alan Bond gave a progress update on the SKYLON programme at the event on 8 Dec. He was able to report that while the pre-cooler development was proceeding slower than hoped; all other research and development work had equaled or surpassed expectation. He also stated that it was likely that funding for the next stage was going to be slightly delayed pending completion of the pre-cooler test programme.

Reaction Engines has published its latest update for November 2011:

• The Final Module
  The 25th and last pre-cooler heat exchanger module to be made as part of the Technology Demonstration Programme was finished this month. The image shows the module entering the brazing furnace. The assembly of the complete pre-cooler, which uses 21 of these modules, is now in its final stages.
• New Production Facility
  Reaction Engines has started its move into a new production facility at the Culham Science Centre. It has over 600 square metres floor area and will house both the company’s heat exchanger development and general fabrication activities during the next phase of the SABRE engine’s development.
• Alan Bond receives the Geoffrey Pardoe Space Award
• John Scott-Scott retires

Photos from the Skylon status update given by Alan Bond of Reaction Engines at the BIS Propulsion meeting held at RAF Cosford last weekend.

Apologies for the poor quality, but I'd drained the battery on my decent camera the previous day and didn't have the charger with me, so I had to resort to using my phone ;p

Some brief notes:-

* Bond described the current structure of the Reaction Engines group, including its manufacturing subsidiaries

* He discussed the complexities involved in manufacturing the very fine tubes required for the pre coolers, and assembling them into the finished modules. The tubes are checked by automated electromagnetic sensors, with any anomalies passed to human inspectors.

* The thermodynamic cycle of the SABRE-3 engine was outlined.

* He showed preliminary photos and videos from the STRICT altitude-compensating nozzle test firings undertaken by Airborne Engineering at Westcott. The use of altitude compensation would cut the typical Skylon takeoff run by 600m.

* Low-NOx combustor development work for the EU-funded LAPCAT programme was described.

* Cryogen plumbing is in place in the B9 test area at Culham in preparation for precooler flow tests

* Bond described objectives of the Phase 3 development programme.
- raise SABRE engine technology to TRL 6 through ground testing
- complete the design of the SABRE 4 to manufacturing drawings
- ensure that the vehicle requirements and SABRE 4 engine design are compatible
- Flight test the nacelle design

It is likely that Phase 3 will grow from the specified 30 months to at least 39 months.

* First images of the proposed Nacelle Test Vehicle were shown. The NTVs are 'one-shot' expendable flight test vehicles, propelled by LOX-methane biprops, and intended for aerodynamic verification of the nacelle geometry. The NTVs appear as 'scaled-down' Skylons, and are 9m long, with a 3.5m wingspan, massing approx 1 tonne each.

* Tests with LOX film cooling of combustion chambers was conducted in conjunction with DLR at Lampoldhausen. The results were very promising.

* Other development work includes: CFD modelling of re-entry heating by DLR. Bond noted that modelled heating levels were remarkably low.

Reaction Engines has posted its latest monthly update:

• LAPCAT combustor: Testing work continues on a low-NOx combustion chamber for the Scimitar engine under the EU-funded LAPCAT programme.
• REL at IAC 2011: REL presented papers on the Skylon and SABRE engine, as well as the use of Skylon as a launch system for lunar bases.

Rocketeer comments: Er, heat exchangers? Oh well, I'll be at the Cosford propulsion meeting this weekend, guess I'll find out more then.

Reaction Engines have posted their latest monthly update for August 2011. They report that preparations for SABRE engine precooler tests continue at the B9 test site at Culham. REL also exhibited at the Power and Production weekend at the Southbank Centre in London, part of the 60th anniversary celebrations of the Festival of Britain.

Flight International says that the engine tests have started: Spaceplane engine tests under way
