                                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 !

Jetcopter could disrupt entire helicopter industry .
Direct competitor of AIRBUS H125 , but with twin engines , engineered for 70% lower operational and 70% lower maintenance costs .
With target price $600,000 against $2 400 000 , new , safe and efficient copter for breakthrow in your business .






Advantages :


1. big capacity - 6+ seats

2. twin hybrid engine redundant construction ( total 1000 kW )

3. higher speed versions possible 

4. big flying distance - 1000 km /620 miles .

5. convenient modular structure - fuselage , motor compartment and turbines interchangeable

6. efficient winged construction

7. safe , parachute equipped 

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 !

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
