Enics is a Research Center that has built UAVs, for example, the E-85 and E-95 models that were motorized with non-valve pulse injectors.

-Like the Snecma models and more concrete like the Ecrevisse (see).

"UAV Enics, modelo E-95"

-The pulsejet on the E-85 gave 40 Kgf and the E-95 one is very similar.

From Appendix 9: UAV vehicle development and construction center. Under the Russian legislation of JSC (Joint Stock Company) it acts as a construction company. Located in Kazan.

"E-95 UAVs lined up"

-The UAV E-95 model has replaced the E-85. In the below illustration we have a new double engine, the M-135, ICABE. It is also without valves and intermittent cycle, that is, Pulsejet.

"The double pulsejet running on a bench"

-For vehicles capable of ascending to an altitude of 3000 meters and reaching 400 km/hr. with full load.

-The following models of Enics are with piston engine and even with electric motors. Maybe to avoid the noise.
