Appendix 3A

REMOTE CONTROLLED HELICOPTERS WITH SURVEILLANCE MILLIMETER-WAVE RADARS WHICH HAVE STATIC COMPONENT OF LIFT FORCE.

The purpose of remote controlled helicopters having addition static lift (hereinafter referred to as a hybrid copter) is to provide operational reconnaissance and observation of the battlefield and work as an artillery guidance system during at least 2 hours each (the set consists of two helicopters which are replacing each other)

For the first time, its concept and circuit design were published by me on 10/11/2011 as a description of the concept of a rescue hybrid helicopter - "helicopters in special aviation having the a static component of lift force"

My special thanks to Dr. Gulia Nurbey Vladimirovich.

It is thanks to his articles, read many years ago, that I became familiar with his idea of "super flywheels" and their application, without which many of problems on the topic of "impact tactical groups" impossible to be solved.

What are the differences between a remotely controlled a hybrid copter with additional static lift (hereinafter referred to as a hybrid copter) and a classic helicopter?

There are two main differences -

during the flight of a hybrid copter, two-thirds of the vehicle's weight is compensated by the static lift of a helium toroidal balloon;

its rotors are made in the form of coaxial impellers that do not have a swashplate, but are capable to be reversing in the direction of rotation or changing the angle of attack of the blades to the opposite.

Such a scheme, firstly, simplifies and reduces the cost of the device, and secondly, it reduces the accident risk from an uncontrolled fall even as a result of serious malfunctions or a decrease in battery charge below the operational level.

In addition to that, the impellers reversing or the angle of attack of the blades changing to the opposite allows you to quickly change the height, removing the device from the enemy's attack.

Horizontal movement is provided either by changing the position of the impellers blinds, or by the interaction a wind flow with a horizontally rotating carrier balloon filled by helium and which is stabilized in two planes (magnus effect).

The standard circuit of movement of the vehicle over the attacking group is a figure-of-eight, with a large axis located across the wind flow and it is performed at height of 2 km.

Since most of this apparatus consists of an optically and radio transparent carrier-balloon; the central module has a radio-absorbing coating; and the apparatus itself is energy provided by flywheels and it has a low heat emission, all of that means that it is difficult to detect it in the air and direct air defense systems or air-based missiles at it.

6 - inlet air flow; 7 - outlet air flow; 8 - flight direction; 9 - direction of rotation

STRUCTURAL CARTRIDGE OF A HYBRID COPTER

2 - skirt of balloon; 13 - structural cartridge

The main structural element of a hybrid copter is the structural cartridge, which has the upper and lower flexible skirts and controlled blinds that directed airflow.

Gyro modules and their accessories are cantilevered inside the structural cartridge.

TOROIDAL CARRIER BALLOON

The toroidal carrier balloon is produced by polyethylene. It has an adhesive layer on the surfaces adjacent to the skirt and can be easily replacement when it is damaged.

Before the launching of a hybrid copter, the carrier balloon is filled with helium, under slight overpressure. After landing of the hybrid copter, helium is pumped out from it into the tanks of the transport platform, and the toroidal carrier balloon and its supple skirts are vacuum-processed and collapses up to a condition of minimum volume.

Carrier balloon weight is 96 kg. When it has diameters: 3.5 m of the outer ring and 4.5 m of the inner ring, its volume is approximately 900.6 m3 and, accordingly, the static load capacity is more than 0.9 tons.

This is 3/4 of the total weight of a hybrid copter at least.

The total flight weight of a hybrid copter is assumption no more than 1400 kg.

Dimensions of a hybrid copter are:

height in the air - 3.5m; height in transport configuration on the ground - 2.2 m;

diameter in the air -15m; diameter in transport configuration on the ground - 3.3m

Antennas of 3D survey locators are folded up in transport configuration and can be placed compactly near the structural cartridge of carrier balloon.

1 - balloon; 2 - skirt of balloon; 3 - controlled blinds; 4 - 3D antenna of the lower hemisphere; 5 - 3D antenna of the upper hemisphere.

The balloon and the survey 3D antennas installed in it can rotate together with the carrier balloon around the internal transport-energy module in the selected direction and at a given speed.

MAIN WORKNG MODULE

A transport-energy module is mounted inside the carrier hub and it provides in the air: stabilization of a hybrid copter ; energy supply and movement in a given direction.

10 - gyro module of horizontal positioning; 11 - gyro module of vertical positioning; 12- battery; 13 - carrier hub

TRANSPORT-ENERGY MODULE

In addition to the general function of energy providing to a hybrid copter, the upper module provides positioning in the horizontal plane and compensation for the mismatch of moments from rotating of impellers and the helium cylinder.

The lower module keeps the device in a stable upright position, in addition.

Emergency battery tanks are installed on both sides of each module.

The impellers are installed on the lower module and, between them, there is a ring that contains their drive and the impeller adjuster of attack angle of blades (it is not a helicopter-type swashplate).

The impellers can rotate both as in opposite directions and as synchronously, relying on the virtual axis of the upper module.

Such a design allows to quickly and safely to drop out fling altitude of a hybrid copter up to the level of the ground effect action (it is up to about a height of 10-25 meters), in the event its attack by air defense.

It gives to a hybrid copter possibility to go out from of a threat of an enemy attack and to implement additional defense capabilities against homing missiles of any type.

GYRO MODULE

The gyro module consist of a light cylindrical body containing two counter-rotating flywheels.

Both the body and flywheels carry out by 3D printed of carbon fiber onto a rotating mandrel. The difference between its parts is only in the manner of weaving threads and the thickness of the constituent elements which are selected depending on the level and direction of the load.

Because the gyro module of a hybrid copter, unlike of the gyro module of the gun platform, does not counterract to a high level of transverse-axial and shock loads, it is simplified.

This module does not have a magneto dynamic flywheel compensation and is lightweight, but rotates with a much higher speed.

During preparation for flight, the module body is vacuumed and then is filled with helium up to 0.5 of atmospheric pressure.

This allows to significantly reduce loses for friction and as result, that reduces unmasking heating.
