Ukrainian Company Scopa Industries is Preparing Shepit Pulse Jet Engine for Flight Tests

The Ukrainian company Scopa Industries is preparing for flight tests of a new jet engine for unmanned aerial vehicles – the Shepit.

A company representative told Militarnyi about the engine at the Brave1 Components exhibition.

This is a domestic model of a pulse jet engine made entirely of Ukrainian components.

At the preliminary stage, the team conducted a series of ground tests to assess the basic characteristics of the engine.

According to the results of these tests, the time of stable operation of the Shepit on the ground is about five minutes.

Engineers note that the main problem with ground launch is the rapid overheating of the structure. Because of this, the engine begins to break down, which limits the duration of its operation in static conditions.

It is expected that in the air, due to cooling by the flow, the Shepit will be able to operate much longer.

According to preliminary data, the approximate speed that the Shepit can reach is about 700 km/h. This figure depends on the aerodynamic characteristics of the airframe on which the engine will be installed.

The design of the Shepit provides for scalable thrust, which allows it to be adapted to UAVs of various sizes – from light reconnaissance to medium-sized strike models.

The engine has a thrust of 18 kg with a dead weight of 6.5 kg. It runs on regular A-95 gasoline, with a consumption of about 1.5 liters per minute.

The dimensions of the Shepit are 1.3 meters long, the diameter of the combustion chamber is 25 cm, and the tail section is 16 cm.

The company emphasizes that simplicity of design and maintenance is one of the main advantages.
