CZ28253U1 - Parachute lifesaving system for unmanned flying means - Google Patents

Description

Technical field

The technical solution concerns the parachute rescue system, especially for small to medium flying unmanned aerial vehicles.

Background Art

The prior art technical solution consists of individual blocks that need to be connected together using connectors and wires. The main components of such a system are a parachute container, control electronics, backup battery, safety locking mechanism. This brings design and installation complexities and can lead to malfunctioning. Representative of known solutions is, for example, U.S. Pat. No. 3,700,192.

The essence of the technical solution

The above-mentioned disadvantages are eliminated by a technical solution where all these components are integrated into one unit. The entire system integrates all the necessary components that are required to function the system. In addition, several other technical solutions are used that contribute to trouble-free and easy use.

The structural arrangement of the present invention consists of a container and an assembly comprising a parachute, a piston, a container lid, a pyrotechnic igniter, a base, a locking pin, an electronics plate, a container bottom and a parachute strap, all parts of the assembly being placed in a container that is divided by a piston to a portion above the piston including the parachute, the container lid and the parachute strap, and a portion below the piston where the igniter, the electronics board, the base, and the locking pin are located.

BRIEF DESCRIPTION OF THE DRAWINGS

The technical solution will be explained in more detail by means of the drawings, in which Fig. 1 shows the overall technical solution of the parachute rescue system in longitudinal section, Fig. 2a shows the top view of the pressure piston serving for parachute extension, Fig. 2b shows the longitudinal section of the piston, Fig. 3a Figure 3b shows an overall view of the container and the locking pin in the retracted state. FIG. 4 is a partial cross-sectional view of the upper portion of the container, and the detail illustrates the reinforcement of the container at the top. FIGS. 5a, 5b and 5c are detail and cross-sectional views of the upper portion of the container where the reinforcement ring is interrupted in order to easily exit the parachute strap from the container.

Examples of technical solutions

The parachute rescue system consists of basic parts, which is a container 1 and an assembly comprising a parachute 2 piston 3, a container lid 4, a pyrotechnic igniter 5, a base 6, a locking pin 7, an electronics plate 8, a container bottom 9 and a parachute strap W. All parts of the assembly are placed in the container 1, which is divided by a piston 3 into a portion above the piston 3 containing the parachute 2, the container lid 4 and the parachute strap 10. In the part below the piston 3 there is an igniter 5, an electronics plate 8, a base 6 and a locking pin 7. The piston 3 has a reinforcement 13 in the center of the piston 3 and is provided with reinforcing ribs 11 for the higher strength. using a reinforced edge 14.

When the parachute rescue system is activated, a signal is sent by the electronics which activates the igniter 5, which by means of an explosion generates a buoyancy force acting on the piston 3 with the center of the bottom 13 of the piston 3 being pushed out and pushes the parachute 2 out of the container I. to avoid losing it. The locking pin 7 serves as a fuse and performs electrical

To shorten the pyrotechnic initiator to prevent it from firing from stray and induced currents or by accidental firing.
