International Aerospace Consulting - Chairman   Prof.Dr. Masataka MAITA

Eugen Sänger (22 September 1905 – 10 February 1964)
The pioneer of Spaceplane (winged access to space vehicle) who inspired us all. Austrian aerospace engineer best known for his contributions to lifting body and ramjet technology.
 












West German concept, Sänger design for a two-stage spaceplane was named after Eugen Sänger.



























With Sänger Program Director, Heribert Kuczera

























Sänger’s remarkable design, the Silbervogel ("Silverbird") have relied on its fuselage creating lift (as a lifting body) to carry it along its sub-orbital path. Sänger also designed the rocket motors that the space-plane would use. In the design, Saenger was one of the first to suggest using the rocket's fuel as a way of cooling the engine, by circulating it around the rocket nozzle before burning it in the engine.
Sänger’s Boost-glide trajectories are a class of spacecraft guidance and reentry trajectories that extend the range of suborbital spaceplanes and reentry vehicles by employing aerodynamic lift in the high upper atmosphere. In most examples, boost-glide roughly doubles the range over the purely ballistic trajectory. In others, a series of skips allows range to be further extended, and leads to the alternate terms skip-glide and skip reentry.
I had chance to see his son in Bremen during the Space Plane and Hypersonic Systems and Technologies Conference in October 2007.


























Gleb Evgeniyevich Lozino-Lozinsky
 (Russian: Глеб Евгеньевич Лозино-Лозинский)

Chief designer & developer of the Russian Space Shuttle Buran.
(Buran ("Буран" in Russian means "Snowstorm") looks similar with US Space Shuttle but is entirely Soviet design. Similar design result is mainly due to the laws of physics and database being the same and shared for all. The main difference is Buran can fly in automatic mode without any pilot on-board from the take-off of the rocket to its landing.)



































I have met Lozino-Lozinsky in Moscow at International Aerospace Congress in 1997. (Gleb as Co-Chair and myself as International Committee MemberBusiness card I received;









He passed away in November, 2001.


Harry A Scott
The Chief Engineer of the National AeroSpace Plane of North American Aviation/Rockwell International and Executive Vice President of Space Access LLC.
2008 recipient of SAE International’s Clarence L. (Kelly) Johnson Aerospace Vehicle Design and Development Award.
During his career, Scott worked on F-86F, F-100D and F-107A fighters, the X-15 rocket plane and was responsible for the innovative design of the Apollo docking gear and made zero-gravity flights to observe astronaut operation of the device.
He created the configuration and proposal design that won the Space Shuttle contract by NASA.










 


















I had several opportunities to have discussions with Harry in person.
My precious memory is Harry’s sketch given to us on our Spaceplane concept based on our explanation. After detailed design works later on, our SSTO Spaceplane design was close to what Harry figured.






























I am keeping in touch with Harry.



















Allan Bond
HOTOL, for Horizontal Take-Off and Landing, was a 1980s British design for SSTO (Single-Stage-To-Orbit) spaceplane that was to be powered by an airbreathing propulsion. Development was being conducted by a consortium led by Rolls-Royce and British Aerospace (BAe) based on the concept by Allan Bond.















However, there was a general attitude of reluctance within the British government to take the lead on a new space launcher.
In 1989, HOTOL co-creator Allan Bond and engineers John Scott-Scott and Richard Varvill formed Reaction Engines Limited (REL) which has since been working on a new airbreahing engine, SABRE which used alterative designs to work around the Rolls-Royce patents, and the Skylon vehicle intended to solve the problems of HOTOL.
has since been developing the core technologies, particularly the engine and its frost-controlled precooler; initially supported by private funding, but latterly with support from the European Space Agency,  UK Space Agency, BAe, and the US Air Force Research LAboratoy. As of 2017 REL plan to demonstrate a flight-ready precooler operating under simulated flight conditions in 2018, and statically test a demonstration engine core in 2020.
