PREAMBLE TO THE DESCRIPTION:
The following specification particularly describes the nature of the invention and the manner in which it is to be performed:

HIGH-G CENTRIFUGE USING RADIAL ENDPOINT VEHICLE
FIELD OF INVENTION:
The present invention relates to high-G training / simulation. Particularly, the present invention relates to a high-G centrifuge using a radial endpoint vehicle. More particularly, the invention relates to a high-G training simulation solution using radial endpoints that propel themselves using E-vehicle (EV) technologies, which are safe, and economical and can evolve continuously.

BACKGROUND OF THE INVENTION:
The following background discussion includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication expressly or implicitly referenced is prior art.
The fighter aircraft and pilots experience high centrifugal forces that are normally expressed as multiples of earth’s gravity (9.8 m/sec2) example: 2G, 4G, and 9G etc. This means that the man and machine are experiencing 2 times, 4 times and 9 times 9.8 m/sec2 of acceleration.
While machines are designed to handle the forces caused by these accelerations, pilots need to be specially trained for these to prevent accidents due to G-induced loss of consciousness, where the brain is denied the required blood flow resulting in loss of consciousness.
There are other applications too that experience high-Gs, such as Formula-1 racing, Space missions, etc. Concerned industries also test equipment likely to be subjected to high-Gs in high-G centrifuges. High-G centrifuges normally can also simulate negative G, which is basically changing the direction of the object under centrifugal force.
Problem of the existing High-G training / simulation solutions:
Centrifugal acceleration is a function of ‘radius*square of angular velocity’ (r?2). Currently high-G centrifuge solutions use a radial arm mounted on a central motor that rotates the cockpit connected at the outdoor endpoint at a high angular velocity.
Example of current high-G centrifuge solution:
A 5 m arm rotating at 2 rad/sec (360 degree/sec) produces 20G. Assuming a 200 Kg cockpit like structure including the structure including the pilot, attached to the end of the arm, it will require more than 75 kW capacity motor to produce such angular velocity.
There are additional requirements of such a set-up such as graceful deceleration during power failures or uninterrupted power to continue the motion, else it will cause injury to the pilot, infrastructure capable of dissipating the eddies caused by the high velocity of radial arm, data and power transmitted to the cockpit at the endpoint via the radial arm, etc. All of which add to the cost and complexity of the solution.
An illustration of typical high-G centrifuge is as shown in figure 1:
M – Central Motor, C – Cockpit, P – Pilot
Figure 1 shows a typical high-G centrifuge (100) of prior art. As shown in Figure 1, the typical high-G centrifuge (100) comprises a central motor (11), cockpit (12) and there is a pilot (14) seated in cockpit (12). The current high-G centrifuge solution uses a radial arm (13) mounted on a central motor (11) that rotates the cockpit (12) connected at the outer endpoint at a high angular velocity. Such as considering a 5 m arm (13) rotating at 2 rad/sec (360 deg/sec) produces 20G and assuming a 200kg cockpit (12) like structure including the pilot (14) attached to the end of the arm (13), it will require more than 75 kW capacity motor to produce such angular velocity. Such set up requires lot of additional equipment to ensure safety and efficiency. It also tends to be expensive to operate. Some of the existing prior arts are as given below:
U.S.A. Patent No. US5051094 discloses a g force trainer or centrifuge wherein a pilot is seated in a gondola mounted on arm and subjected to g forces approximating those the pilot would encounter in a real aircraft. A g force trainer comprising a shaft driven by a motor in response to motion control signals, a tubular arm secured to the shaft for rotation therewith about the shaft axis, a yoke secured to the arm, and a gondola mounted at the yoke so as to roll about a horizontal axis in proportion to the speed of rotation of the arm about the shaft axis.
U.S.A. Patent No. US9824605B2 discloses a centrifuge-based-flight simulator. The centrifuge-based simulators of prior arts include a cockpit unit, a motion unit and an arm. Cockpit unit is a compartment connected to a centrifuge arm. Cockpit unit is configured to spin around a central portion of simulator providing planetary motion and impart enhanced gravity (G) forces on a pilot/trainee inside cockpit unit. Actual G-forces imparted on the trainee are dependent upon the length of arm, a distance cockpit unit is from central portion, and a velocity cockpit unit spins around central portion (i.e., planetary velocity). Cockpit unit is also configured to spin around an independent axis to replicating ±360 degrees of movement in yaw, pitch and roll axes.
The above high-G centrifuges of existing prior arts are based on single central motor, and such set up requires a lot of additional equipment to ensure safety and efficiency. The additional requirements comprise graceful deceleration during power failures or uninterrupted power to continue the motion else it will cause injury to the pilot; infrastructure capable of dissipating the eddies caused by high velocity of radial arm, data and power transmitted to the cockpit at the endpoint via the radial arm, etc. All of these requirements add to the cost and complexity of the solution.
The problem of the prior arts may be considered as that such set-up requires a lot of additional equipment to ensure safety and efficiency, and it tends to be expensive to operate. The solution to the problem of prior art is provided by the present invention.
The present invention provides a high-G training/simulation solution using radial endpoints that propel themselves using E-vehicle (EV) technologies, which are safe, economical, and can evolve continuously. Particularly, the present invention provides a high-G centrifuge using radial endpoint vehicle. Instead of mounting the cockpit on a long arm and then rotating the whole mass at high RPMs, the solution of the present invention uses the end-point’s own power to propel itself in a circular motion.

In present invention, instead of mounting the cockpit on a long arm and then rotating the whole mass at high RPMs, the solution uses the endpoints or power to propel itself in a circular motion.
Figure 2 shows the illustration of high-G centrifuge (200) using radial endpoint vehicle wherein Ch – Chassis, P – Pilot, W – Wheels of the chassis.
The high-G centrifuge (200) of the present invention comprises a chassis (21) assembled on track (23). The track (23) can be enclosed on horizontally and/or vertically stacked rails. The cable (27) to the center (26) of circle is to provide reliable data connection. The reliable data connection helps the IoS (Instructor Op System) to operate and monitor the simulated flight from outside, the reliable data connection is required between the cockpit and IoS. This is also used to capture aeromedical data.
As shown in expanded view of chassis (21) in right-hand side part of Figure 2, the chassis (21) as a holding structure is mounted on wheels (25) with its own propulsion system. The propulsion system is a programmable electric propulsion that can be controlled both from internal pilot and external pilot driving the holding structure forward. A cockpit (22) with 1 to 6 degrees of freedom (DOF), depending on the requirement, is attached to the holding structure i.e., chassis (21). The shape of the cockpit (22) can be spherical or any of other polygonal 3D structure to accommodate different layouts. A pilot (24) is seated in the cockpit (22).
Modern electric vehicle (EV) technology can achieve 60 mph in less than 2 seconds. For example: - The Tesla Roadster is an upcoming battery-electric four-seater sports car to be built by Tesla. The company has said that it will be capable of accelerating from 0 to 60 mph in 1.9 seconds.
Given the curb weight of the above example at 1.3MTs, it is possible to have a chassis with 1 to 6 degrees of freedom (DOF) single/multi-crew cockpit.
In an embodiment, the present invention provides a design of high-G centrifuge (200) as shown in figure 2, using a radial endpoint vehicle comprising a holding structure (a chassis) (21) mounted on wheels (25) with its own propulsion system. A programmable electric propulsion system that can be controlled both from the internal pilot and from the external pilot driving the holding structure forward. The track (23) can be enclosed on horizontally and/or vertically stacked rails. The track stacking on horizontal and vertical rails provides advantage of traction. At rest or slow speeds, due to gravity, the wheels on horizontal track will have more traction. As the speed increases the wheels on vertical track will have increased traction due to centrifugal force. So, both horizontal and vertical tracks are used in the present invention. Further, the cockpit (22) shape can be spherical or any other polygonal 3D structure to accommodate different layouts. The cockpit (22) has 1 to 6 degrees of freedom (DOF), depending on the requirement, attached to the holding structure (a chassis) (21).
In an embodiment, figure 3 is a 3D illustration of figure 2, the additional components are the rails on floor and a canopy (which will be full 360 above the rails) to offer 2nd layer of safety in addition to the rails.
In an embodiment, the present invention provides the high-G centrifuge using radial endpoint vehicle with several advantages like it avoids the need for a high-powered and expensive central motor. Further, it avoids the need for backup power and deceleration mechanisms and less infrastructure is needed. In another advantage it reduces the high mechanical load concentrated at the centre and is distributed along the circumference.
In an embodiment, the present invention system has low weight and low operating cost and easy to change simulated aircraft.
In an embodiment, the present invention system has electric rails to provide electric connection to the High G vehicle.
In another embodiment, the present invention system can train multiple pilots simultaneously by attaching multiple end points together like a train. In the train type system of the present invention data and power come from centre to one endpoint and the rest of the endpoints are connected in daisy chain.
