The Samara State University of Railways has registered a patent for a method of controlling the flight of a rocket. Presumably, this will reduce the missile’s approach time to the target and create conditions that make it as difficult as possible to detect the location of the munition.
The device itself is placed in the immediate vicinity of the enemy’s territory in a place hidden from enemy detection devices, under water, at a depth of 100-300 meters from the ocean surface. There it can be delivered by submarine. It will swim as close to the target as possible, and then unload the rocket closer to the surface.
The device is made with a base made in the form of a “table” with equipment with nozzles of running motors for moving the installation. The rocket is launched from a depth of 100 meters. If it is lower, it is raised by running compressed air under the cylinders in the pistons. The air begins to push the cylinders up, so that the structure rushes to the surface.
When the rocket enters the surface position, the main engine is turned on, and its flight begins along a pre-calculated trajectory. The installation without the rocket is lowered back to the underwater position. Before this, the air from the lifting cylinders is re-pumped into the compressed air tank for future rocket lifts.
The flight control of the rocket is carried out according to the program recorded in the onboard computer of the rocket. If there are deviations of the actual trajectory from the program, the flight of the rocket is corrected with the participation of the satellite navigation system.
The proposed method differs from the standard methods in that the missile is located close to the enemy, but first it flies along a false trajectory and only then turns to the target. Thus, it becomes less detectable.
To change the course, the radio station of the device is turned on to receive at times according to a pre-arranged schedule and is additionally turned on by order from the command post. The antenna of the radio station is constantly in the underwater position and pops up only when the radio station is operating, and the radio station itself and the computer are placed on the base of the platform. This reduces the chance of signal interception.
At the request of the command post, the radio station can transmit the coordinates of the location of the device and report on the serviceability of the condition using a computer and a satellite navigation system receiver. When receiving information from the command post, the computer selects the route, as well as with the participation of the onboard computer, selects the target and time of the rocket launch.The coordinates are transmitted to the command post with the planned distortions. To get the actual coordinate values, you need to know the correction factors, which are set in advance and depend on the date and time of day. This is a kind of cipher, thanks to which the enemy is less likely to know where the rocket will fly.
