It's time for modern helicopter !
helicopters 100 years in use without major changes
disadvantages : no parachute , no wings , high price , complex construction , many single points of failure , loud , fuel inefficient , complex piloting , long time preparation for take off , dangerous large blades , expensive maintenance , huge operating costs - $1400/h
advantage : big rotor need less power for take off
This is not propeller !
4 years old design

8. engineered for easy scale for mass production ( 5000+ units per year )
9. very low maintenance and passenger per mile costs
10. affordable price - just 30% of same size helicopter
11. very maneuverable - mandatory and huge advantage for city flights
12. patent protected
Jet stream always wins
too many samples today where more powerful and efficient jet stream overcome simple stream . Propelled VTOL's are temporary solution , axial jet turbines for airplanes , radial fans - for next gen copters !
LOST WIN
LOST WIN
Jet stream for new aplications
This is not a propeller :
Video about how radial fan works very well in the air
RADIAL FANS PRESSURE POWER SAMPLE
Only 4 X 400 cm radial fans were able to lift 320 000 kg weight hovercraft .
Despite ground effect require less power , radial force at bigger RPM is extremely powerful .
PATENTED CONSTRUCTION
USA patent , publication US-2019-0016453-A1
replacing main and tail rotor by double centrifugal air turbines
replacing cyclic control by airflow vectoring
4 points airflow vectoring instead complex swash plate
practically proven Harrier jump jet 4 nozzles thrust vectoring system
Almost all modern VTOL constructions were tested long time ago and ... failed
Presently it's boom of VTOL designs , majority of them are just recalls from 1950's , second attempt to bring them to life . Today only too lazy not offered own VTOL aircraft design and there are reason - electric motors . Looks so simple - just add 4 rotors + motors around the cabin and here we have - new aircraft . But reality is not so simple .
Why not multicopters ?
1st multicopter law : as smaller rotors are , as more powerful motors you will need .
2nd multicopter law : more rotors = more motors = more problems
3rd multicopter law : more rotors = more air drag
Why Jetcopter will be more efficient VTOL ?
JETcopter will be able to use air lifting power , helicopter not .
JETcopter evolution
Engine : 2 x automotive with duplicated fuel , cooling , power supply systems .
Reliable and less mechanically complex
no swash plates , no cyclic , no hydraulics , no clutch .
Take off : helicopter mode or plane mode , fly as plane
will be able to land at auto parking ,
will be able to maneuver safe between cars
powered by reliable automotive motors ,
may not need helicopter pilot licence
much easier to pilot
Low production costs ( compared with 6 place helicopter ) :
Operational costs predicted 60-70 % lower than helicopter
better aerodynamics , better functionality
equipped with 2 parachute life saving system
fuselage all made from carbon fiber
