SYSTEMS AND METHODS FOR IMPROVED VEHICLES CONTROL
Document Type and Number:
WIPO Patent Application WO/2021/066666
Kind Code:
A1
Abstract:
The present application relates to an airborne vehicle comprising a towing vehicle and a towed vehicle or person connected to and towed by the towing vehicle through a lightweight construction. The drag of towed vehicle or person creates a force through the lightweight construction behind the point of the center of gravity of the towing vehicle. The counter force of said force (thrust) directs the towed vehicle or person into the direction of lightweight construction and the towing vehicle. The towing vehicle is composed of at least one wing surface and a drive group with propulsion unit, stabilizing and control surfaces and a communication control system. The pilot in the towed vehicle or the person can control the moving direction of the towing vehicle - thereby the flying direction of the whole vehicle - through the lightweight structure.

Description:
SYSTEMS AND METHODS FOR IMPROVED VEHICLES CONTROL

FIELD OF THE INVENTION

The invention more broadly belongs to the field of control of vehicles moving through fluids and on a hard surface. In the discovery that follows, we will show it through aviation, aircraft with a spherical construction, class B64C 15/12, B64C 29/00, B64C 39/06, B64C 39/08. Physics class G05B 1/04, G05D 1/08, G01C 9/00, carrying and / or can pull at least one person and / or payload, moving on a hard surface and through the air with great agility and freedom of movement.

SOLVING TECHNICAL PROBLEM

From ancient times, people have strived for greater freedom of movement through the air, water and on land, as well as by sending a payload to a desired destination.

BACKGROUND OF THE INVENTION

People have come up with various ways to move as freely as possible, as shown in patent applications:

• US 2,180,922 a solution that is very unsafe for the user, the environment and not feasible until the recent level of technological development.

• US 2,847,173 the solution is also very unsafe for the user and the environment.

• US 2,953,321 a very inefficient solution and not feasible until the recent level of technological development. US 3, 113,747 solution of major control problems, due to aerodynamic forces, because only the control of the propulsion system was used.

Or more recently:

• US 6,634,593 solution applicable to micro aircraft, without solving the problem of transporting cargo larger than a few kilograms.

• JP 4,899,069 B2 also a solution applicable to micro aircraft, without solving the problem of transport of cargo larger than a few kilograms and manual transport of the aircraft by the operator on a hard surface.

• US20180208312A1 a solution that meets the minimum transport requirements of one person but is extremely loud. Completely unusable in urban areas.

SUMMARY OF THE INVENTION

This discovery relates to improved steering and increased vehicle stability by shifting the primary steering system and payload behind a propulsion system with a secondary steering system (one unit that may be autonomous). The drive and towed part of the vehicle connected by a light construction whose main role is the transmission of forces, energy and information. The primary and secondary management systems can work in unison, independently or if only one is operational.

A small percentage of vehicles have a separate part of the vehicle behind the drive part of the vehicle, but no known vehicle has a separate part of the vehicle with the primary steering system behind the drive - traction part of the vehicle with secondary steering.

Since this control steering system is applicable to different types and categories of vehicles, a more detailed explanation follows on the example of the ultra-light VTOL aircraft, an optimized spherical shape of the propulsion part.

The main features of the spherical structure of the propulsion part of the aircraft are:

> to ensure the safety of users and the environment during operation

> to provide a safe border line when moving in an urban or environment with close proximity to other objects > When moving it on the ground, easily and safely roll the aircraft around the propulsion axis.

In the spherical propulsion part of the aircraft there is at least one wing surface, at least two control systems, at least one propulsion system with its components, communication and navigation system and other systems that thus form one independent functional aircraft, which is looking broadly the propulsion part of the aircraft. At least one fluid reservoir and at least one propulsion system is housed in the hull and wing cavities.

The lightweight construction that connects the drive and towed part of the vehicle is composed of at least one elongated segment that can be of different flexibility and length. In this example, a rigid cable with electrical installation consisting of power, communication and control lines.

As a towed part of an aircraft with a primary steering control system, it will be shown here as, one person (may be more) who primarily controls aircraft with the displacement of his body using aerodynamic forces and through the front interface control secondary steering system on the towing aircraft. The towed part of the vehicle can also be a payload space in for example the shape of a wing segment with a minimum of two steering systems.

Steering of the towing vehicle (30) is realize in such a way that the towed vehicle (35) shifts its mass in space and by moving it towards the desired direction, directs the towing vehicle (30), which may or may not correct its direction by its secondary steering. Towing vehicle (30) orformation of towing vehicles (30) with secondary steering control (Fig. 16, 3 circles, one example of formation (33)) towing another part of the vehicle (35) which has the primary function of steering the whole system (30), (15), (35) in the desirable direction.

So that the vehicle (35) transmits the force and creates a moment of force relative to the point of gravity of the vehicle (30) by the connected position behind the center of gravity of the vehicle (30) and thus creating a moment of force which corrects the vehicle (30) in the direction of light construction (15). Proportionately depending on the magnitude of that moment of force, the system will have a faster response, the less torque and the response of the direction control command will be slower.

Such a system of movement can be applied in different physical environments, for example:

1. On the water, a water scooter (30) (a small speedboat without a driver going only forward) for which a skier (35) is attached with a rope (15). By moving his body or ski, the skier turns left or right by transferring the force to the towing vehicle (30) behind the position of the center of gravity of that vehicle and thus creating a moment of force that corrects the vehicle (30) in the direction of the rope (15).

2. In the water, a torpedo would be a towing vehicle (30) to which a rope (15) was attached and a diver would be a towed vehicle (35) steering by moving his fins (34).

3. In space Figure 14, two unmanned rockets (30) in front, connected to a larger system by a rigid link (31 ) pull an asteroid in that image in the shape of an airplane, while a third manned rocket a circle behind the aircraft. Connected by a line, a towing vehicle 30), which here has the role of control surfaces 34, controls the movement of the direction, creating a moment of force transmitted to the traction rockets (30), (31 )

4. In air, the movement of the towing vehicle system (30), the lightweight structure connecting them (15) and the towed vehicle (35) (payload) or at least one pilot (20) will be explained in detail below.

An example of the application of the shape and function of a towing vehicle (30) would be to function as a wheel of a vehicle moving on a hard surface by rotating around the axis of the holder (42) transmitting force to the hull (1) rolling on the protective belt around the propeller (2). Connected to the vehicle at the point of attachment, where the light construction (15) is. When it needs to take off, the wheels (30) would separate and be connected by light construction 15 to the vehicle (30), then take off in, for example, a formation (33). This would be very economical and practical to apply to robots that explore other planets or celestial bodies, such as Mars and Titan.
