Projectile and method for stopping aerial vehicles
A projectile and method for stopping aerial vehicles. The projectile comprises a shell—and a bunch of filaments. The bunch is wound in a coil and placed inside the shell. The projectile according to the solution may be brought to a target by different methods and utilising different means. For example, the projectile may be fired with compressed air or a propulsion charge, by using a compressed air weapon or rocket launcher. In addition, the projectile may be taken to the target by using a rocket or aerial vehicle.
1. A projectile comprising
a shell and
a bunch of filaments,
the bunch of filaments being wound in a coil and placed inside the shell,
wherein
the filaments are of carbon fibre and the filament bunch is a carbon fibre tow comprising at least 1000 filaments.
2. The projectile as claimed in claim 1 , wherein the filaments comprised by the bunch are fastened together substantially at one end.
3. The projectile as claimed in claim 1 , wherein the filament bunch 50000 filaments, at the most.
4. The projectile as claimed in claim 1 , wherein the filament bunch comprises 10000 to 30000 filaments.
5. The projectile as claimed in claim 1 , wherein filament bunch has a length of 8 to 16 metres.
6. The projectile as claimed in claim 1 , wherein an outer diameter of the projectile is 40 to 120 mm.
7. The projectile as claimed in claim 1 , wherein the projectile further comprises a packing plate to which the filament bunch is coupled.
8. The projectile as claimed in claim 7 , wherein the packing plate ( 110 ) is of plastic, cardboard, paper, or paperboard.
9. The projectile as claimed in claim 7 , wherein the filament coil formed by the filament bunch wound in a coil and the packing plate are mutually parallel.
10. The projectile as claimed in claim 7 , wherein the filament bunch is fixed at one end to the centre part of the packing plate.
11. The projectile as claimed in claim 1 , wherein at least three filament coils are placed inside the shell.
12. The projectile as claimed in claim 1 , wherein the projectile further comprises means to open the shell.
13. The projectile as claimed in claim 1 , wherein the projectile further comprises a propulsion charge and a case as its outermost part.
14. A method for stopping aerial vehicles, the method comprising forming an obstacle in the air by making use of a projectile comprising
a shell and
a bunch of filaments,
the bunch being wound in a coil and
the bunch being placed inside the shell,
whereby the filaments are of carbon fibre and the filament bunch is a carbon fibre tow comprising at least 1000 filaments.
