Abstract

1. Устройство для защиты двигателя от попадания посторонних предметов, содержащее ротор с перфорированными лопатками, установленными перед двигателем, отличающееся тем, что, с целью уменьшения потерь полного давления на входе в двигатель и необходимой мощности привода, перфорированные отверстия в каждой лопатке выполнены в виде радиальных щелей, наклоненных к продольной оси ротора под острым углом в направлении, противоположном наклону лопатки.2. Устройство по п.1, отличающееся тем, что угол наклона щели к продольной оси ротора выполнен в интервале от 10 в корневой части до 24° в периферийной части.1. Device to protect the engine from ingress of foreign objects, containing a rotor with perforated blades installed in front of the engine, characterized in that, in order to reduce the loss of total pressure at the engine inlet and the required drive power, the perforated holes in each blade are made in the form of radial slots, inclined to the longitudinal axis of the rotor at an acute angle in the direction opposite to the inclination of the blade. The device according to claim 1, characterized in that the angle of inclination of the slit to the longitudinal axis of the rotor is made in the range from 10 in the root to 24 ° in the peripheral part.
