REAL FIRST RESPONDERS

If all those who participate in the application of liquid hydrogen to the future of flight, do their job right, then the whole world will find a new type of “cargo-wagon” pulled by a much more efficient “horsepower” that would be based on the universal generation of hydrogen from water. That would be using wind, solar, and most importantly micro-nuclear reactors capable of supplying cheap energy to continuously make hydrogen for $1/kilo. Who really needs that? “Manhattan Project” investors in NYC? NO… The whole, warming globe will need millions of flying pickup trucks to deal with hurricanes, tornadoes, snowstorms, floods, droughts, forest fires, massive migrations, mega-city-civil-rioting and global political changes.

LH2 CRYO-COPTER GUTS

SHOWN HERE IS THE FIRST DESIGN FOR LH2 TANKING INTEGRATED WITH A SUPER-CONDUCTING MOTOR DRIVING QUIET SINGLE LIFT FAN FOR FUTURE VTOLS .

WHO ARE THE CONSORTIA CONTRIBUTORS? 

Why must the electric motors be made of super-conductors?.

This “HUB” is the digital home of diverse innovators working for the next 10 years, cooperatively on the same, singular mission objective. That is not to save the global atmosphere, but to deliver “EMERGENCY VEHICLES” needed to deal with all the disasters that will be created by climate change. These innovators (gov agencies, Universities, big and small corporations and especially AGGRESIVE investors) will be using funds from various charitable R&D trusts as well as tax free city/state development “bonds” to be sold over the next decade.

Most VTOL innovations exploit the “toy-quad-copter” concept of multiple motors (& propellers) based on the high power per kilo of weight available from permanent magnet DC motors. Key to that aircraft design strategy has been the 4, or 5 or 6 (or more) “DC-power plants changing the current (RPM speed) to the motors, and/or changing the prop’s angle of attack. That works well for staying in a hover mode, but that is very inefficient, so all VTOLs now promote the rapis transition of leaving the hover configuration (for take off) and moving forward horizontally. The Joby aircraft tilts its well designed lift-fan propellers, from vertical to horizontal for efficient forward flight. Others simply shut down the multi-motor “lift function” and stability of many horizontal motors, and at sufficient altitude, turn on a forward thrust(s) to enable typical “wing” structures to provide efficient lift, for maximum travel distance on a given Gigajoule of stored energy. Liquid Hydrogen will change that dynamic. It permits a single (or 2 or 3, or 4) lift fan of much LARGER dimension, with LOTS of lift fan blades (more than 5), to provide excellent HOVER efficiency by SLOWLY rotating the unique thrust-fan which, in turn, slows the downdraft airflow and hence the level of noise during near-ground hover. Adding to that, the best aerodynamic efficiency would be to put the lift-fan into a duct, and the best of that is to have two counter-rotating fans in a proper ducting (akin to Bell’s solution). The end result is HOVERING EFFICIENCY, especially with lots of stored energy, is the breakthrough.

WHAT CAN WE SAY HERE? (QUOTES STUF) 

The history of electric powered VTOL flight was in the hands of Mike Hirschberg, editor of “Vertifilte” the association magazine/website for the Vertical Flight Society. (he is seated third from the right (dark business jacket) at the table of innovators who launched the TRANSFORMATIONAL VTOL consortium. On the far left seat of the table, (in his white “smoking”) is the “GODFATHER” of hydrogen powered VTOL aircraft R&D, based on nearly 50 years of obsessive commitment to the subject, starting in 1970 when working effectively as a “venture capitalist” in the Central Research Labs of the 3M company (which has had a LOT to do with the materials issue of cryogenic insulation, fuel cell PEMs, aircraft fabrication adhesives, etc.)
