Deployable observer and radio transmission drone

Nowadays, warfare is based on communication capabilities that make the use of specialized ability units possible in coordinated ways, and among other things, gathering information for decision making. So, the drones with observational and communication capabilities has become a significant part of modern warfare.

This type of drone would basically be a remote-controlled electric helicopter, which could be launched from below an aircraft wing, thanks to its foldable structure, for example using the universal underwing pylon of the C-130 Hercules.

This kind of drone would work on the ground, the helicopter mode should only be for deploying.

Simplified structural diagram:

1. The body of the drone would consist of two main parts, this lower part would contain the batteries. Thus the drone’s center of gravity will be low, what is important for its stability.
2. The upper main part of the body would include the communication and control subunits, the radios, the GPS receiver, the flight con…


There are tens of thousands of indoor and outdoor shooting ranges in the world, where shooting is practiced on a wide range of targets, but I think it would be worth using smart targets to expand the training possibilities further.

The Gunslingers would be a separate app that anyone could install on a smartphone. The app could connect to this smart target, making it possible to play game in an Old West gunfight. The player must defeat ten gunslingers in the game, who would become more and more difficult opponents.

Simplified structural diagram of the smart target:

1. The structure of the smart target can be different sizes, but the most common size would be the human size. The frame of the smart target would not be bulletproof, because the players can only use rubber bullets.

2. Two pairs of light curtain sensors would be integrated into the frame, which sensitivity would be adjusted to the size of the projectiles. One of the sensor pairs would be vertically embedded, so when a projec…

Firefighting airship

At residential areas without an unlimited supply of water to extinguish fire, or at unoccupied areas without proper infrastructure, extinguishing extensive bush and forest fire is often an unsolvable task, because the opportunities of the delivery of the extinguishing material to the target location are always limited, independently of the number of the available tanker trucks or firefighting aircrafts.

The modern version of the legendary, ocean liner-sized Graf Zeppelin filled with helium instead of hydrogen would also be capable of transporting extinguishing material, because its payload capacity similar to firefighting aircrafts. However, because of its significantly lower airspeed, it would be able to carry out turns too slowly.

Nevertheless, the airships’ ability of hovering at one place makes the on-the-spot creation of the extinguishing material possible instead of transporting those to the fires.

This new type of firefighting airship, which could have the length of three hundred…
