"Can be held by the IEs of Ukraine": Russians boast of foam drone MM-1

The foam absorbs and scatters radio waves, which makes it almost invisible in the sky. So far, only one MM-1 drone has been collected in the Russian Federation, but they will soon make more. Russian engineers said they created a drone made of foam called MM-1, which is not terrible any means of radio electronic wrestling or radar systems. About it reports the agency of the Russian information agency TASS.

According to a representative of the Innovation and Technology Center TSAGISTART, located on the territory of the technopark of the Central Air Airhydrodynamic Institute named after Professor M. E. Zhukovsky, in the design of the drone there are virtually no metal parts, which makes the drone as invisible as possible. Only the engine is made of metal and a limited number of screws of the main nodes of the drone.

However, if metal screws create problems with the HR, the developers can replace them with fiberglass mount. According to the TASS Agency TSAGISTARTArt, the MM-1 drone can develop speeds of up to 100 km/h, while carrying a useful load up to 5 kg. In this case, the drone is controlled in the FPV mode (with a first person view) and is equipped with a special camera. So far, MM-1 exists in a single copy, but in the near future engineers are preparing to gather five more such drones.

The developers plan to achieve the maximum unrecognizability of the drone systems of the HRs and will make the necessary modifications during the tests. According to the UAS Vision portal, the cellular foam structure is a big problem for radio electronic fighting and various radars. When radio waves are confronted with foam, they are absorbed, scattered or reflected by numerous air filled with voids inside the material.

Such scattering and absorption of radio waves complicates the accurate detection or reading of signals by radio frequency devices from objects or labels covered or surrounded by foam material. In addition, plastic polymers used in foam can also have a shielding effect on radio frequency signals. Some plastic polymers, especially with high conductivity or metal additives, can block or weaken radio waves. This further complicates the ability of radio frequency devices to detect foam.
