Truck Drone Pegasus
The PEGASUS vertical take-off and landing cargo drone, with a payload of 50 kg, is a quadrocopter type, with control by changing the pitch of the propellers, in the basic version, equipped with a single drive from an internal combustion engine.

The used transmission scheme provides good values of the specific share of the payload, which when using a rotary-piston engine is 0.6 of the total weight of the device.

  1. Version of the landing/take-off – vertical.
  2. Flight range, mile, not less than 124.
  3. Static ceiling, ft, no more than 13 123.
  4. Traction power (at the ground), not less than 1.5÷2
  5. Maximum permissible wind speed, ft/sec, no more than 98.
  6. Maximum flight speed (in horizontal flight), miles/h, at least 49.
  7. Flight time, min, not less than 180.
  8. Payload weight, kg, no more than 50.
  9. Weight of the loaded vehicle, pounds, no more than 176.
The PEGASUS is a quadrocopter with vertical take-off and landing capabilities. It is controlled by changing the pitch of its propellers alongside a cargo drone that has a payload of 110 pounds. In the most simplistic version, it is equipped with a single drive from an internal combustion engine.
The used transmission schema yields great value from the specific share of the payload, which when using a rotary-piston engine comprises 0.6 of the total weight of the device.
Structurally, the device is designed according to the scheme of the "H" - Shaped Quadrocopter.

The Fuselage (our box-type) contains a fuel tank (with a capacity of 30 liters), as well as a strategically placed instrument compartment. The basic version is equipped with a two-cylinder engine, with forced air cooling.

The Design of the Transmission, if necessary, allows you to use a drive engine that is compatible with a variety of engines (e.g., electric, internal combustion engine piston, hybrid, turbojet, Wankel, etc.).

Lifting and Traction Propellers reduce the aerodynamic drag of the vehicle in either a horizontal flight or rotary.

To compensate for the possible displacement of the center of mass, the Angle of Rotation (in the rear pair of screws) may differ from the angle of rotation (in the front pair of screws) more or less, depending primarily upon the direction of displacement in reference to the center of mass.

The Payload is placed (attached) at the bottom of the fuselage or on its side surfaces.

The Devices are controlled by changing the pitch of the screws.

The Torque from the Main Engine, en route to the main screws, is distributed from a single shaft located under the instrument compartment and fuel tank.

The Device's Consoles are removable, which significantly diminishes the requirements for the size of the transport container.

To ensure reliability, it is possible to use four different control systems including:

• A Radio Control System (AM) from a ground station with a carrier frequency of 433 MHz and
a maximum range of up to 200 km (radio horizon);

• A Data Management and Transmission System (including video data) via mobile communication channels (GSM) communications, 4G and 5G generation -- with coverage area action;

• A System for Managing and Transmitting Data (including video data) via commercial networks,
satellite systems (e.g., Inmarsat, Globalstar, Iridium, Thuraya, Eutelsat, etc.), and in the future (~3-5 years) via the global Internet (e.g., Iridium Communications Inc, Starlink, OneWeb, Samsung, LeoSat, Boeing, Telesat, Hongyun [CASIC], etc.), which will provide limitless global coverage in terms of range and communication with the device;

• An Inertial Control System that determines the behavior of the device when an emergency event takes place.

The specific type of control system and the possibility of duplicating them is determined jointly with the customer at the stage of forming a preliminary technical specification.
The Payload is diverse and represents:

1. Optical Means of Monitoring the Earth's Surface (e.g., optical heads, high-resolution aerial cameras, panoramic cameras, high-power lidars, etc.);

2. Radar Means for Monitoring the Earth's Surface (e.g., lateral and circular view locators, meteorological locators, electronic warfare equipment, etc.);

3. Sonar Buoys;

4. Special-Purpose Cargo (e.g., ammunition, special-purpose cluster munitions, etc.);

5. Containers for both dry and liquid cargo;

6. Civil Cargo (e.g., temporary housing, rescue equipment, dry cargo and liquid cargo [e.g., chemical fertilizers for processing up to 6 ha of crops], etc.);

7. Search and Rescue Equipment (e.g., searchlights, lighting chandeliers, etc.);

8. Transport Car Trailer
The PEGASUS Cargo Unmanned Aerial Vehicle, with its technical capabilities, has many possible applications, including the traditional ones inherent in "small" unmanned aerial vehicles with a payload of up to 22 pounds.

The Most Popular of the Application Options Are the Following:

• Optical Monitoring of the Earth's Surface

• Radar Monitoring for the Earth's Surface and Surrounding Areas

• Search and Rescue
