Battery operated flying car with enclosed motors for human transportation

Abstract

“Battery operated flying car with enclosed motors for human transportation” is machine that can carry humans and looks like a real flying car. The current problem with implementing this is resolved by using ducted motors with grilles around it. By covering top and bottom of car with grilles we are able to negate effect of completely covered motors. By providing grilles around motors we ensure safety of humans around it, this not only avoids direct contact but also provides continuous air flow into motors to push out from the other side. Loss of efficiency due to covered grilles are countered by use of two additional front and two rear motors. Vertically mounted front motors push air into bottom motors which significantly improves the lift capacity of the flying car. Vertically mounted rear motor pumps air out of the car and thus aids in forward movement of the flying car.

DETAILED DESCRIPTION

A. Overview

(9) The key part of the invention is enclosing the motors and propellers in within safety cages to allow the flow of air in and out of the motors but at the same time reduce human injury from exposed propellers and compensating for loss of air intake by providing front and/or rear motors also enclosed in cages.

(10) Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the figures illustrate an example embodiment comprising the four bottom motors to provide thrust, the two front motors to push air into the fuselage, the two rear motors for forward and backward movement in the air, the airframe to support all the components, the battery to provide power, the duct work to supply air, the passenger cabin with the console, the avionics and the complete framework enclosed within a covered body with grilles for air passage preventing injury to humans.

B. Bottom Motors

(11) There should be four motors in the bottom of the car, mounted on top of the airframe. The motors should be configured to pull air from the top and push it downwards to provide lift for the flying car. Each of the motor is a heavy lift brushless motor. Each of the motor propeller combination is enclosed with grille covers to prevent injury to humans.

C. Front Motors

(12) The front motors pull outside air and push into the flying car so that the bottom motors have enough air to push down for thrust. Each of the motor is a heavy lift brushless motor. Each of the motor propeller combination is enclosed with grille covers to prevent injury to humans.

D. Rear Motors

(13) The rear motors pull air from the front of the car and push it out of the rear of the car there by providing forward thrust for the car to move forward in the air. Each of the motor is a heavy lift brushless motor. Each of the motor propeller combination is enclosed with grille covers to prevent injury to humans.

E. Airframe

(14) The airframe is the core structure to which all the load is attached. The airframe connects all the motors, the battery bay, passenger cabin and the wheels together. The air frame should be made of ultra-light high strength materials like carbon composite. Carbon composite high strength airframe rated for 1,000 lbs. of load.

F. Battery

(15) The flying car will be powered by a battery power source similar to lithium or other power storage options. The batteries will be mounted on battery bay attached to the airframe and protects the passengers in the cabin above with a firewall in between.

G. Duct Work

(16) Air ducts will be used to isolate and channel the air from the front of the car to the bottom motors and the rear motors. Low weight Aluminum or plastic duct work.

H. Passenger Cabin

(17) The passenger cabin will be attached to the airframe and be above the battery bay insulated by a firewall to protect the passengers in case of fire in the battery. Futuristic looking passenger cabin with touch sensitive LCD screens for console, throttle for takeoff and landing control. Multi directional Joy stick for Forward, backward, left and right controls.

K. Alternative Embodiments of Invention

(20) The key part of the invention is enclosing the motors and propellers in within safety cages to allow the flow of air in and out of the motors but at the same time reduce human injury from exposed propellers and compensating for loss of air intake by providing front and/or rear motors also enclosed in cages. Provided below are variations of applying this invention.

(21) Variation 1: Flying car with four bottom, two front and two rear motors. The car body to have air intake grilles all over to maximize air availability for the bottom motors and also to reduce stress on the car frame. This is the most efficient configuration with maximum lift and payload capacity.

(22) Variation 2: Flying car with 4 bottom motors and 2 front motors.

(23) In this variation there is reduction in two rear motors. The front motor will have to perform added work of forward and backward movements along with pumping in air for the bottom motors for lift. The reduction in two motors should be compensated with additional air intake grilles on the car body. This is the second best option, this option reduce the over length of the car, reduces the lift power and payload capacity is reduced.

(24) Variation 3: Flying car with 4 bottom motors and 2 rear motors.

(25) In this variation there is reduction in two front motors. The rear motor will primarily assist in forward and backward movement of the car. The reduction in two motors should be compensated with additional air intake grilles on the car body. This is the third best option, this option further reduces the over length of the car, but also reduces the lift and payload capacity further.

(26) Variation 4: Flying car with four bottom motors only without the front and rear motors.

(27) Additional intake grilles in the sides, top and bottom of the car will compensate for the loss of the front and rear motors. The bottom motors will be used for take off, landing as well as forward and backward movements. This is the least best option, this option further provides the shortest car but also reduces the lift and payload capacity and lift drops significantly.

(28) Variation 5: Each of the above variations are available in single passenger and double passenger variation.

L. Operation of Preferred Embodiment

(29) Completely enclosed motors with grilles on the enclosure to prevent contact of the propellers with humans to avoid any injury. Forward/backward, left/right is controlled by mechanical flaps/rudders on the car. The controller will be one joy stick on the right of the dashboard. The user has full control over this. Up and down is controlled by aircraft style throttle (left of joy stick). Speed and brakes are controlled by foot pedals like in a car. 4 wheels, non-powered with connected brakes. Non-retractable. Batteries spread out across the bottom of the fuselage.
