Reaction Engines update February 2010

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.

The latest in the highly-acclaimed edumanga series from No Starch Press, The Manga Guide to the Universe explores the Universe, with the aid of manga cartoons. The story revolves around three students who develop an interest in the Universe after listening to a Japanese folktale about a girl from the Moon. The girls enlist Kanta, an astronomy major, to teach them more about the Universe.
The Manga Guide to the Universe begins with an overview of how ancient cultures thought about and studied the Sun, Moon, and stars, coupled with an overview of important astronomical work by Copernicus, Gallileo, and other seminal astronomers. Kanta explains how our solar system works; how we calculate distance in space; the Big Bang Theory; and theories about the Universe's evolution and cosmic expansion. Readers explore the Milky Way, faraway galaxies, supernovas, quasars, and black holes, as well as the history of space exploration, including the Moon landing, the launch of the International Space Station, and the Hubble Space Telescope--all with the aid of original Manga cartoons. This edumanga title is co-published with Ohmsha, Ltd. of Tokyo, Japan, and is one in a series of translations from Ohmsha's bestselling Japanese originals.

UoSAT-2 transmitting for 26 years
Rocketeer — Sun, 07/03/2010 - 1:11am
(Source: SSTL press release, 1st March 2010)
Twenty-six years ago today the University of Surrey team led by future SSTL-founder Sir Martin Sweeting launched the UoSAT-2 satellite (a.k.a UO-11) onboard a Delta rocket with LandSat-D from Vandenberg Air Force Base, USA on the 1st March 1984.
The 60kg small satellite was built in just 6 months and carried a Digitalker speech synthesiser and experiments including magnetometers, a CCD camera, a Geiger-Müller tube and a microphone to detect micrometeoroid impacts.
UoSAT-2 was instrumental in providing a communications link from the Canadian-Soviet Ski-Trek support teams to the expedition party in 1986. The position of the skiers' emergency beacon was calculated daily by Cospas-Sarsat ground stations and relayed to them and thousands of amateur radio listeners as a spoken message from the Digitalker on board UO-11. This is really worth a listen - visit the expedition web page. The message could also serve as an emergency channel to the skiers in the event that all other radio links failed.
UoSAT-2 also carried the Digital Communications Experiment (DCE) that was the first digital packet store-&-forward payload on a microsatellite. Find out more about this payload and see some photos of UoSAT-2 being built at Lloyd Wood’s personal UoSAT-2 pages.
The plucky small satellite was still transmitting last week on 145.825 MHz AFSK-FM at 1200 bps after 26 years in orbit! The small demonstration satellite’s on-board batteries are exhausted after 26 years in orbit, so the satellite now only operates in sunlight and has inactive beacons at 435.025 MHz and 2401 MHz.

The latest issue of the Space IGT newsletter is available for download.
Of particular interest is the following:-
The Space SIG website is set to receive a fresh new look with additional tools for enabling online networking. The Connect Portal, brought to you by the Technology Strategy Board will replace the existing infrastructure creating clear and easy mechanisms for you to work across the Space SIG and KTN landscape. This includes:
- A network of networks – enabling the exchange of ideas from one discipline to another and in the process finding new and surprising ways of innovating.
- Building social networks online – a powerful way to gain the benefits of membership and to help you develop productive relationships for innovation.
We will inform you of the registration details for the new network so you can benefit from this exciting new platform.
Rocketeer comments: I'm solidly in favour of improved networking in the UK space science and technology sector. This falls in the category of "why the hell didn't you do this before?!".
Travelling at the Edge of Space: James Weir Lecture

Alan Bond, Managing Director of Reaction Engines Limited will deliver the first James Weir Lecture, titled "Travelling at the edge of space: Reaction Engines and Skylon in the next 20 years".
This seminar will be in Court Senate suite from 1730 hrs on 10 March 2010. To register for attendence please email Fiona Lynn.
Abstract
The use of liquid hydrogen to cool the air entering a high speed aircraft engine has been in the literature for fifty years, but was not developed because of the high fuel flow required. In the early 1980s it was found that if the fuel was not used simply as coolant, but as the heat sink for the engine driving the intake compressor while using the hot stagnated air as its heat source, the fuel consumption was greatly reduced. Reaction Engines has been evolving these engines for over 20 years resulting in designs for the SKYLON spaceplane, and engines suitable for Mach 5 civil airliners. The next twenty years should see the pre-cooled engine transform access to space and flight to the antipodes. This talk describes Reaction Engines R&D programme and its ambitions for the future.

UK plans world's first nuclear fusion power station [update]
Rocketeer — Fri, 26/02/2010 - 8:29am
(Source: Times Online, link via NextBigFuture)
BRITISH scientists have drawn up plans to build the world’s first nuclear fusion power station. They say it could be pouring electricity into the National Grid within 20 years.
Nuclear fusion, the power that lies at the heart of the sun, offers the prospect of clean, safe, carbon-free power with a minimum of radioactive waste. But despite decades of research the technical problems have seemed insurmountable.
This weekend, however, Research Councils UK (RCUK), which oversees the British government’s spending on science and technology, has said it believes that many of those obstacles are close to being overcome.
It wants to commit Britain to a 20-year research and construction plan that would see a fusion power station in operation around 2030. Didcot in Oxfordshire is among the sites under consideration for the so-called Hiper project.
“The potential of fusion energy to contribute to the future global energy system is sufficiently large that it should be pursued in the UK,” said a report published by RCUK.
It also follows the recent start-up of America’s National Ignition Facility, in California, which has been designed to demonstrate the principle of laser fusion. There, 192 giant lasers have been installed, collectively capable of generating 500 trillion watts — 1,000 times the power of the US national grid — for a fraction of a second.
That energy will be focused on a tiny fuel pellet of frozen hydrogen which, in theory, should be compressed and heated to 100mC — so hot that the atoms within it start to fuse.
“The world is watching and waiting to see what happens at NIF,” said the report, calling this “a seminal moment” in the development of fusion.
Mike Dunne, project co-ordinator for Hiper, agreed. “The NIF laser is performing well — they have already achieved fusion reactions but so far they are putting in much more energy than they are getting out.
“The crucial test will come this autumn when they ramp up the power. In theory they should start generating more power than they put in and if that happens it will be a clear demonstration to the world that laser fusion is ready to be harnessed. So far the signs are very good.”

UPDATE
The Expert Group convened by RCUK to help develop our UK fusion for energy strategy concluded that:
"The science and engineering research challenges ahead to realise fusion as a commercial energy source are major and the timescales are long and uncertain. Fusion is likely to contribute to energy systems after 2050."
Hah. Surprise.
IOW: Fusion is the energy source of the future... and always will be :-p
