TASS, June 25th. The National Space Company together with a group of specialists in the field of rocket engineering conducted tests at a special test site in Kirov region.

According to the company, the launch will be included in the Russian Book of Records, as no one in the CIS countries has done this. The missile took off at a height of 15 kilometers. Its speed is Mach 2, i.e. almost 2500 km/h (which is twice as fast as the sound speed).

The "Vyatka" rocket is a classic two-stage construction. The missile's design includes: a control system (SC), a multi-channel telemetry system for rescue of the second stage, a search system, a control system and a video fixation system.  The height of the missile is 3 meters. There are ailerons on the missile's surface.

The first stage has a solid propellant rocket engine (SPRT) with an impulse of 8000 N*s. The second stage RDTT has an impulse of 5000 N*s.

The launch of the engines is controlled by the onboard control system. Before the second stage is started, the control system monitors the vertical speed. If the missile reaches the horizon, the second stage engine is not launched.

The missile has a two-stage rescue system for the second stage. It consists of two parachutes. The first exhaust parachute opens at apogee, performs a braking function and reduces the missile's falling speed to 30 m/s. The second parachute opens at an altitude of 1 km from the ground surface. It has a dome shape with a diameter of 1500 mm and reduces the fall speed of the second stage to 5 m/s.

The search system consists of three independent beacons. The first beacon is located in the missile's head fairing, records and transmits to ground equipment GPS coordinates at an interval of 3 seconds. The second beacon operates at a lower interval and transmits the coordinates to the radio station. The third beacon is based on GSM module. This from the SU was transmitted to operators of quadrocopters, which in real time tracking the direction of flight of the missile and video fixation.

When searching for the second stage of the GSM module did not give any results, because there was no cellular communication in the launch area.

In the design of a suborbital missile it is planned to install a rescue system for the first stage.

According to General Director of the National Space Company Maxim Kulikov, no private space company in the CIS countries has ever done this. Kulikov said the rocket engine was tested earlier.

"Our company plans to launch a real suborbital missile. All these are crucial steps for the National Space Company in building and launching the Siberian launch vehicle, which will deliver up to 1 ton of cargo into orbit and become a successful commercial project. We are confident in this," Kulikov said.

It's worth noting that Vyatka is a prototype of a suborbital missile, which the National Space Company plans to launch soon at an altitude of 100km (which is already the border of real space; before launch, approval from Roskosmos and obtaining a license are required). This work is currently under way. Teachers and students of specialized universities, in addition to the scientific community, will be invited to the trials.

During the tests, the on-board telemetry systems, step separation system, rescue and search system were successfully tested.

The natural testing of the prototype was successful; the next stage will be the launch of a suborbital rocket for 100 km using a liquid propellant rocket engine.
