Abstract

Vertical takeoff flying machine comprises of a circular body (1), securely housing 32 aerodynamic blades (4) housed within the ducting (8) (Figs 4, 5), each rotor blade has a metal cup (7) connected to the end of the rotor blade, also connected to the rotor blade 4 is the pitch adjustment arm (9) (Fig 5), the hydraulic ram (11) when operated pushes the metal ring up against the wheel on the pitch adjustment arm (10) allowing the rotor blade (4) to alter its pitch, when thrust from the jet engine (6) is directed into the ducting (8) the metal cups (7) will rotate 360 degrees in their duct housing (8), when this is in operation. This will allow the aerodynamic blades to gain sufficient lift to raise the flying machine into the air to the required height. The propeller (3) will hold the body in a stable position, then by altering the pitch of the rotor blades (4) forward motion will be achieved. <IMAGE>

Description

"VERTICAL TAKE-OFF FLYING MACHINE MARK 2" This invention relates to flying machines. there are two basic types,namely the fixed wing aeroplane provide with forward drive engines and the helicopter,which is supported and driven by large rotating blades,each of these designs has advantages over the-other,in particular the helicopter has the facility for vertical take-off thus removing the need for a run way it does have limitations in size and forward speed compared with a conventional aeroplane.

It is an object of this invention to provide a flying machine which can combine advantages which are separately provided in the designs of a conventional aeroplane and a helicopter.

Accordingly this invention provides a flying machine comprising a body portion which has a circular inner cabin portion and passenger area, connected to the outer rim of the circular body there are thirty two rotor blades connected to a drive ring.

This drive ring has a series of cups which are also connected to the drive housing within the ducting which has a gap on the outer side where the rotor blades are connected to the drive ring in combination with a thrust of the Jet engine will provide a lifting force to the machine when the drive ring is caused to rotate.

The drive ring incorporating the aerodynamic aerofoil blades can be formed as a very robust construction securely housed for rotation within the body portion of the machine.

When rotated at high speed,the drive ring and aerodynamic aerofoil can provide substantial uplift to the machine enabling the machine to take offvertically,when the machine has reached the required height the rotor blades pitch maybe altered enabling the machine to move forward through th air.

The rotor blades are driven by a Jet engine,the thrust of the Jet engine is directed into the ducting,housing the cups on the main drive ring as in the fashion of a water wheel,forcing the drive ring to rotate giving sufficient speed for the rotor aerodynamic blades to gain the appropriate uplift and pressure.

The invention may be performed in various ways and preferred impediments thereof will now be described with with reference to the accompanying drawings,in which; Figures 1 to 3 are respectively a perspective view and a side view of one form of flying machine of this invention; Figure 4 is a plan view of the machine shown fom above showing a cut away version of the cups No 7,inside the ducting No 8,with arrows No 9,indicating the flow of the thrust of the Jet engine No 6,which enables. the machine to take off vertically and hover no 1 on figure 4 relates to the body of the machine incorporating the cockpit cabin and passenger area on the main body of the machine No 5,relates to observation windows, No 4 relates to rotary blades No 3 relates to propeller blades on the main fin No 2,No 13 relates to the main drive ring being attached to the cups No 7,and the aerofoils No 4.

Figure 5 relates to a cross cut section of the main body No l,showing the cups No 7,inside the ducting No 8, with the rotor blades No 4, No 9 relates to the control arm that alters the pitch of the rotor blades,No 4,No 10 relates to the wheel attached to the control arm No 9,on the rotor blade No 4,No 11 being an hydraulic arm pushes up No 12 a circular platform for wheel No 10 to ride on, allowing No 9, by means of the wheel No 10,to alter the pitch of the rotor blade allowing the machine to gain horizontal and vertical flight.

Figure 6 relates to a cross side view of cups No 7, and the connecting drive ring No 13, the rotor blades No 4, and the pitch adjusting arm No 9, and duct No 8, No 14 relates to ducting channelling directing Jet engine thrust enabling the cups No 7, to rotate in a circular motion around the outer rim of the main body No 1, of the machine.

Figure 7 relates to the Jet engine No 6, which is situated on the underneath side of the main body No 1, that when in operation the thrust of the Jet engine No 6, will force the drive ring No 13, incorporating the cups No 7 to rotate in a circular motion enabling the aerodynamic aerofoils No 4, to give sufficient lift for the machine to rise in the air to the required height.

Figure 8 relates to an overall side view of the machine parked on the ground showing No 15 landing wheels, No 16 passenger gangway No 17 people boarding to give idea of relative scale in relationship to the flying machine overall scale.

The design of flying machine shown in the drawings provides a number of substantial advantages over conventional aircraft. Firstly the machine can take - off vertically so that runways are not required. The amount of power needed to lift the machine by operating the jet engine No 6, is much less than needed for a conventional aircraft. Once the flying machine is in the air and on its journey only one of the Jet engines will need to be in operation leaving the second engine in reserve for back up, in a conventional helicopter the vast majority have two and sometimes three rotor blades, enabling it to lift itself into the air at will carrying a considerable weight. The design of my flying machine has thirty two rotor blades as described in figure 1 No4, and this possibly could be increased to 64 blades allowing this flying machine to lift itself hundreds of passengers and freight as easily as a conventional helicopter flies today enabling this flying machine to take off and land outside any city in any country in the world.

Claims

1/ THE VERTICAL TAKEOFF FLYING MACHINE COMPRISES OF A CIRCULAR BODY CONSTRUCTION SECURELY CONSTRUCTED FOR THE ROTATION OF THE ROTOR BLADES HOUSED WITHIN THE CIRCULAR BODY, THE ROTOR BLADES BEING OF AERODYNAMIC SHAPE AND WHEN PITCHED AT THE RIGHT ANGLE AND ROTATED AT HIGH SPEED WILL PROVIDE SUFFICIENT UPLIFT BY MEANS OF THE AERODYNAMIC SHAPED RQTOR BLADES FOR THE CIRCULAR BODY TO RISE INTO THE AIR,THIS IS ACHIEVED BY THE THRUST OF TWO JET ENGINES HOUSED BENEATH THE BODY HAVING ITS THRUST DIRECTED INTO DUCTING CONSTRUCTED IN 360 DEGREES AROUND THE INTERIOR EDGE OF THE MAIN BODY. INSIDE THE DUCTING ARE 180 DEGREE METAL CUPS EACH ONE.BEING CONNECTED TO THE END OF A ROTOR BLADE ON THE MAIN DRIVE RING,ALSO THE PITCH ADJUSTMENT ARM WHICH IS CONNECTED TO EACH ROTOR BLADE WITHIN THE CONSTRUCTION OF THE BODY. BENEATH THE PITCH ADJUSTMENT ARM IS AN HYDRAULIC RAM SUPPORTING A 360 DEGREE METAL RING,WHEN THE HYDRAULIC ARM IS OPERATED IT PUSHES THE 360 DEGREE METAL RING UP WHICH IN TURN PUSHES THE ROTOR BLADE ADJUSTMENT ARM UP,THUS CHANGING THE PITCH OF THE ROTOR BLADES ENABLING THE FLYING MACHINE TO RISE INTO THE AIR TO THE REQUIRED HEIGHT,AND THEN BY ALTERING THE PITCH OF THE ROTOR BLADES TO THE REQUIRED ANGLE GIVING THE FLYING MACHINE FORWARD MOTION.
