The technical solutions to reduce noise level in engines of power plants were reviewed in the work. The review on priority of the projects directed to solve the problems of air vehicle acoustic reduction proceeding from evaluation of the main requirements of Strategic Research and Innovation Agenda of ACARE was presented. One of the main directions of research within Flightpath 2050 (goal 9) is a rational integration of airframe elements and power plant. The evaluation results of research initiatives as for the problem to reduce noise of GTE were substantiated according to program Flightpath 2050. On the grounds of the analytical data it was estimated that electrical airplanes and Open Rotor engines characterized by higher efficiency compared to bypass engines with a high bypass ratio (m=50...70) would further develop to a new level by 2050. It was marked that the aircraft with a distributed electrical power plant could essentially influence the solution of the problem to reduce noise of power plants in future.
