David AshfordFounder and Managing Director
Expendable Launch Vehicle(Derived from Ballistic Missiles)
Airliner
Typical Cost per Seat, £ 20 million
(To orbit)
500 (Long distance flight)
Saunders Roe SR.53 rocket fighter
• The Saunders Roe SR.53 rocket fighter first flew in 1957
• This technology has never been bettered!
• Saunders Roe proposed a suborbital space research conversion in 1958!
AIR
Suborbital≈ 1 km/sec max speed100 km

Bristol Spaceplanes Limited
• 1991-Founded
– To exploit the then 30 years spaceplane design experience of its founder
• 1993-Feasibility study of Spacecab small orbital spaceplane from ESA
• 2003-DTI Smart award for feasibility study of Ascender small sub-orbital spaceplane
• 2011-Grant from Technology Strategy Board
• 2013-Study Contract from UK Space Agency
• Development and marketing strategies with lowest cost and risk
– For you to judge!
• Looking for strategic partners
– Superb opportunities for low-cost entry into large new markets
• www.bristolspaceplanes.com
Excellent Engineering Team
• Engineering team includes:
– ex Chief Designer, Leopard
– ex Chief Engineer, Kestrel
CMC Leopard Kestrel

Airliner ‘Conversion’
• Change shape
• Add rocket engines
• Higher propellant mass fraction
• Two stages
• Hydrogen fuel
• Additional systems (reaction controls, thermal protection)
• Safety of rocket propulsion system
ALL THE REQUIRED TECHNOLOGIES HAVE BEEN DEMONSTRATED IN FLIGHT!
Spacebus
Airliners
Cost per Flight, £million 0.2 0.5
Number of Seats 400 50
Cost per Seat, £ (Typical) 500 10,000

Space Tourism Market Survey
• What percentage of UK population would pay £20,000 for a few
days in a space hotel?
– Seeing Earth from afar
– Zero-g
– Clear views of space
– (Astronauts can’t wait to fly again)
• 0.1%?
• 1%?
• 10%?
Potential Market for Space Tourism
• Say 5% of world’s industrialised population would pay £20K for a ‘once-in-a-lifetime’ few days in a space hotel
• Number of tourists = 5% of one billion, or 50 million
• A fleet of 150 spaceplanes with a 50 seat capacity and capable of 2 flights per day would carry them in ten years
• Market = £20K x 50 million = £1 Trillion
Spaceplanes Could Have Been Built 60 Years Ago!

Evolution
V-2 & Derivatives Thor IRBM & Derivatives
To the Moon Shuttle
First to Mach 1, Bell X-1, 1947
First to Mach 2, Douglas Skyrocket, 1953
First to Mach 3, Bell X-2, 1956
First to space, X-15, 1961
US Rocket Research Aircraft
Shuttle Concepts, Early 1970s
Space Shuttle
Cost per flight & accident rate ≈ 10,000 times that of a large Airliner
Breakthrough!
• The first privately-funded spaceplane, SpaceShipOne, reached space in 2004
• Virgin Galactic plan to operate a developed version soon
• Slowly but surely, this and other developments will lead to new space age
Major Players, Suborbital
SpaceShipTwo on WhiteKnightTwo
EADS Rocketplane
Xcor Lynx
Armadillo Aerospace Test Vehicle
Saturn 51960s
SLS2020s
The Main Obstacle is Mind-Set
• NASA, ESA still developing expendable launchers even though spaceplanes would reduce costs ten times in the short term
• Major players not yet taking spaceplanes seriously

Ascender Trajectory
Ascender Has Many Applications
• Microgravity Experiments
• High Altitude Photography
• Meteorology
• Space Science, Testing Satellite Instruments
• Spaceplane Technology Test Bed
• Astronaut Training
• Passenger Space Experience Flights
• Lower stage of launcher for nanosatellites
Spacecab
• Pioneering space tourism for the wealthy (already started)
• Funding to develop lower-cost space transportation (aeroplanes
instead of missiles)
• Airline travel to orbit (1000 times launch cost reduction)
– Low-cost environmental monitoring from space
– Boost for Hydrogen Economy
– Experimental Solar Power Satellites and the beginning of access
to the unlimited resources of space
– Large-scale space tourism (initial demand ≈ one trillion €)
• Increased environmental awareness
