Welcome to Jetcopter !


Helicopters invented in 1920's , Jetcopter reinvented them after 100 years !



                                  Why Jetcopter ?




* one of most compact VTOL projects in the world due ussing ducted centrifugal air turbines 

* more safe to passengers and to people nearby - will have fully ducted fans .

* more efficient  in horizontal flights , will have wings , pusher propeller 

* more affordable compared with 5 seats helicopters

* feasible construction and effective production costs

* many other advantages to be added ...




VTOL AIRCRAFTS HISTORY


It's a long story to explain why some VTOL aircraft construction can be better than other . Too much of different  VTOL constructions presented this days . Majority of them are just recalls of 1950's , second attempt to bring them to life .







                  Below we will explain why JETCOPTER will be better VTOL aircraft 

          ( it will take a time to add all info )


JETCOPTER will take off powered by electric motors ( 2 electric motors per rotor for redundancy and safety ) , after aircraft will take off in 10 m , the pusher propeller powered by automotive piston motor will start to push aircraft forward . Electric motors will be used for short time -  take off and landing 15 min + 15 min . In flight batteries will be charged by automotive motor .




 PROPULSION SYSTEM - CENTRIFUGAL AIR TURBINE vs AXIAL





Automotive piston motors + electric motors vs turboshaft


Power : 300 kW , weight - 135 kg ,

price -250 000$

TBO - 3000 h



4 cylinder piston : 312 kW , weight -160 kg ,

price - 12000$

TBO - 8000 h


electric motor : 260 kW , weight - 50 kg
Batteries weight for 30 min :        kg
TBO - 20 000 h




                                       Urban flights will require additional capabilities as VTOL aircrafts will operate close to pedestrians and buildings.

                                                               Why not multicopters ?




As less rotors aircraft have , as more reliable and less power requiring aircraft is.


1st multicopters law :    smaller rotors require much more powerful motors.


Average helicopter rotor is 12 m diameter , it's 113 m2 disc area !

Most of multicopters have up to 2m diameter rotors , which have 3 m2 or smaller disc area !

That is 37 times smaller than helicopter !

They must have 37 x  rotors to get enough lifting power !

The smaller is rotor disc area - more power you will need for take off .

More power = more motors = more controllers = more batteries = more weight = short flying time .

Why Jetcopter will be more efficient VTOL ?



JETcopter will be able to use air lifting power , helicopter not  . 



JETcopter evolution 



Engine  :


       
 2 x 450 hp  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









Production costs ( compared with 6 place helicopter ) :

 rotors  -   70 %  cheaper 

carbon fiber fuselage - 50 % cheaper

 motors - 90 % cheaper






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
