Reaction Engines

UK company researching air-breathing rocket propulsion and SSTO development.

Reaction Engines update February 2010

Rocketeer — Mon, 08/03/2010 - 1:07pm

Company News

The D1 redesign of SKYLON is progressing well. The preliminary trajectory analysis has been fed into a preliminary configuration analysis to establish how the vehicle will be trimmed in aerodynamic flight. This is the start of an iterative cycle of performance analysis and configuration definition with increasing refinement and detail which will lead to the final D1 definition.

Work has started on the payload provision based on the interfaces proposed in Revision 1 of the SKYLON Users’ Manual. The public consultation produced no suggestions for any changes whatsoever (which was a bit of a surprise) so as a consequence those interfaces are now being worked into the D1 vehicle design.

Work also started on defining D1’s Auxiliary Propulsion System. This system performs many functions on SKYLON; orbit manoeuvring, reaction control, the supply reactants to both the fuel cells and hydraulic power unit, and heat absorption during re-entry. As part of this work, Lolan Naicker of Cranfield University will conduct a postgraduate research project as part of his MSc Astronautics and Space Engineering looking at the SOMA engine which provides SKYLON’s orbit manoeuvring propulsion.

The first firm results from the Reaction Engines trade mission to the USA (as reported last month) came in February with the placing of a small study contract with the Physical Science Laboratory at the New Mexico State University. NMSU will be undertaking a preliminary evaluation of the requirements that SKYLON D1 will need to meet for safe autonomous flight based on their extensive heritage with unmanned flight vehicles, their expert knowledge of the US National Airspace System, and their expertise and experience in the Global Airspace System.

General News

On 10th February at the QEII Conference Centre in London, the Space Innovation and Growth Team (Space IGT) released a report by the Space industry to advise Government on future Space policy. REL contributed to the report entitled ‘A UK Space Innovation and Growth Strategy 2010 – 2030’ and had a small exhibition stand in the foyer at the opening. SKYLON featured in the promotional movie as seen on the BNSC website.

Reaction Engines update January 2010

Rocketeer — Tue, 23/02/2010 - 1:03am

(Source: Reaction Engines)

A small trade delegation from Reaction Engines toured the southern States of America at the end of January. The trip was organised by a United Kingdom Trade and Investment (UKTI) team based at the British Consulate in Houston. The trip included Louisiana, New Mexico and Texas and eight meetings making contact with fourteen companies and government organisations. There was considerable interest in SKYLON and many areas of possible cooperation are being explored further as a result. We would like to thank all our hosts for their very warm hospitality and to the UKTI for the superb organisation.

This trip is now even more significant after Barack Obama cancelled NASA’s Constellation programme which aimed to put astronauts on the Moon by 2020.

The team (left to right: Alan Bond REL, Mark Hempsell REL, Sam Hutchison REL, George Abbey Jr UKTI) at the Neutral Buoyancy Training Facility at NASA JSC, Houston.

REL started the D1 reconfiguration of SKYLON this month and the preliminary trajectory calculations have gone well.

During January the tank for the helium boiler inner spiral wound test coil was delivered. The heat transfer trials will commence in March.

The prototype manufacturing facility team has now performed a 100% inspection of almost 5000 tubes to detect any faults and flaws.

General News

REL welcomed Daniel Kent to the company this month. As Production Controller he will be based at the prototype manufacturing facility.

Rocketeer comments: Also covered by Hyperbola. Given the greater emphasis on commercial spaceflight and the increased opportunities for new technology development funding for launcher systems in Bolden's plans, this visit seems particularly timely. Best of luck to REL in any collaborations they may form. I expect that there will be a number of US companies very eager to get their hands on the airbreathing technology of the SABRE engine.

Reaction Engines update December 2009

Rocketeer — Fri, 08/01/2010 - 3:10pm

(Source: Reaction Engines)

Company News

Our new 1:18 scale SABRE engine model was completed in December, once again by Gemini Prototyping Ltd. This new model will showcase the SABRE engine at many more events as it is more easily transportable.

A helium boiler inner spiral wound test coil has also been manufactured by Ashcroft Welding and Fabrication Ltd. The test coil is made from stainless steel and is certified for working up to 200 bars. This test coil will enable heat transfer measurements to take place ready for the construction of the boiler required to reject heat from the helium loop from the pre-cooler.

General News

REL welcomed Richard Garriott, astronaut and CEO of Space Adventures Ltd, and Nick Spall, Space writer, to our Head Office this month. Both visitors toured our new permanent exhibition area and Richard Garriott told us what it is like to go to Space! Fantastic!

Lastly, our Christmas party was a great night; even Alan had his dancing shoes on!

Reaction Engines: Company acquisitions, SSP report

Rocketeer — Fri, 18/12/2009 - 6:58pm

(Source: Reaction Engines)

Reaction Engines Ltd has recently acquired two new manufacturing companies in the local area:

  • Crossman Engineering Ltd, specialising in fabrication
  • Brite Precision, (specialising) in precision machining.

The acquisition of both companies has significantly extended Reaction Engines Ltd’s production capabilities, which is essential to our future programme for SKYLON.

The ECM Machines at our heat exchanger production facility have now been assembled and commissioned; they are functioning as expected.

We moved premises at the beginning of this month and are now located upstairs in the Innovation Centre with much more space!

REL was featured in the November 2009 issue of the BIS Spaceflight magazine.

Reaction Engines update October 2009

Rocketeer — Mon, 02/11/2009 - 5:21pm

(Source: Reaction Engines)

This October the 60th International Astronautical Congress was held in the city of Daejeon, South Korea and Reaction Engines used the event to launch the SKYLON Users’ Manual. The Manual describes the payload bay interfaces and supplementary systems like upper stages and personnel module that enhance the capability of the basic SKYLON vehicle.

Mark Hempsell presented three papers explaining the background to the Manual and these supplementary systems.

Reaction Engines was also part of the small UK pavilion at the trade exhibition that accompanies the Congress showing the SKYLON operations video and offering hardcopies of the Users’ Manual. The photograph shows the stand manned by Simon Feast who designed it.

Website News

In support of the release of the SKYLON Users' Manual (available in the PDF Documents section), a new library of images of the various payload bay components has been created, containing images of all the items in medium and high resolution.

Skylon: Interview with Richard Varvill of Reaction Engines

Rocketeer — Sat, 31/10/2009 - 9:50pm

Next Big Future features an interview with Richard Varvill, Technical Director of Reaction Engines, on their plans for the Skylon SSTO.

One interesting update: " The Orbital Base Station on the website was designed as part of Project Troy and is sized to provide an assembly facility for the human mission to Mars. We have also looked at supporting Solar Power Satellites, nuclear waste disposal, human lunar missions again all looking good. This OBS will not be the first station to be built when SKYLON becomes operational and the details of the cost and logistics flow have only been looked at superficially. We are looking in more detail at smaller and more imminent space stations and the results of that study – which will answers the questions of cost and maintenance flow, will be ready in about a year."

On 1st October 2009 Reaction Engines opened their new factory in Abingdon, Oxfordshire. This is a major step forward in their development of a revolutionary new engine that will allow practical space planes to be developed.

Alan Bond, Managing Director of Reaction Engines, thanked the BNSC for helping to obtain the ESA grant of 1 million Euros in February this year which is helping to fund the company’s on-going research into heat exchanger technology.

Mr Bond explained the advanced manufacturing processes the company has developed, "The principal focus is the manufacturing process of heat exchangers where tube drawing and electro-chemical machining are combined to produce the required components. RELs heat exchangers are on the leading edge of technology and, when complete, will be the most advanced known of in the world".

The picture shows Mr Bond watching Nick Cox (BNSC) and Gordon Harrison (REL's Engineering Manager who has masterminded the set up of the new factory) cut the ribbon.
