have confirmed that the full engine can now be demonstrated. The SABRE engine has the potential to revolutionise our lives in the 21st century in the way the jet engine did in the 20th Century. This is the proudest moment of my life.” In July 2013 the UK Coalition government announced its intention to invest £60 million ($90 million) into the full development of the SABRE engine, creating 21,000 jobs in the UK aerospace and space sectors. This will maximise the UK’s access into the high growth £13.8 billion ($20.7 billion) launcher market over the next 30 years with all the associated economic benefits rippling out from this investment. The initial £60 million will prime the pump for the remainder of the investment ($360 million) to £360 million ($540 million), and will now include the construction of a full-scale working version o f SABRE. The potential game-changing characteristics of Bond’s SABRE engine have finally been recognised. REL estimates it would cost around £8 billion ($12 billion) to develop Skylon itself. That is comparable to the development costs of the Airbus A380 or the Ariane 5 manufactured by Astrium. Initial Skylon launches would cost about £23 million ($35 million) but that could fall by as much as £7 million ($10 million) as more Skylons are brought onto market. It seems that confidence in the capacity for British engineering has grown again. Since the cancellation An artist’s rendering of the Skylon spacecraft in flight. capital needed to fully develop the SABRE engine and will be divested over 2013-16 to REL. The SABRE development programme itself is expected to last from 3-5 years. A prototype SABRE engine is expected in 2017 with flight tests around 2020. In August 2013 ESA funded a £0.9 million ($1.35 million) study, by a consortium of companies to establish a business case for Skylon’s operation in the satellite launcher market from 2020 onwards. In November 2013 Bond himself announced that the upcoming development phase of Skylon will be expanded from £240 million 54 54 Image: Reaction Engines of HOTOL in the late 1980’s, the same technology has been refined and re-accepted by the current UK government. Simultaneously, while the demand for satellite launches has increased, the high cost and unreliability of conventional rocket launches has not improved by the same pace. The world is ready for something new and timing is everything. Inheriting the crown As for Alan Bond, this decades long odyssey to develop an enabling technology and a viable spacecraft for economic and reliable access to space has become a very personal journey. He has spent many years working in the wilderness due to lack of governmental foresight and support but, like all great engineering visionaries has stayed dedicated to his idea and doing whatever it takes to realise that idea. With a wider overview away from Skylon, Bond believes in a greater journey for humanity with longer strides beyond the Moon with more advanced propulsion. Skylon is a way to take those first steps. “What is absolutely clear to me is that the human race and its petty squabbles are confined to one piece of debris near a fairly ordinary star. “Without easy access to the abundant resources of space, the human race can never sustain Western standards of living and a growing global population. Getting into space is not just what longhaired scientists do as a bit of fun. It’s something that’s absolutely crucial to the continuing progress of the human race.” Bond’s history with the development of SABRE and Skylon echoes that of Sir Frank Whittle, inventor of the turbojet engine. Whittle himself demonstrated an early aptitude for engineering and also without the UK Air Ministry’s support in his time, formed a company with limited funds to develop the first prototype jet engine. The Jet Age began shortly after and made the world the much more interconnected place we live in today. Considered in a BBC poll as one of the 100 Greatest Britons, Whittle’s legacy remains intact today. Bond is on the way to echoing Whittle’s success and creating his own legacy with the advent of a new age in spaceflight. His is a story of overcoming adversity, skepticism, winning over governmental intransigence and defeating the Official Secrets Act, to realise his ambitions. It appears today that he is on the threshold of his personal dream, to reach Earth orbit in a single giant leap. www.RocketSTEM.org
