FIELD: aircraft engineering.SUBSTANCE: proposed air intake comprises chute, intake opening inclined to aircraft crosswise plane at 20-25 degrees, internal curved duct and engine spinner. Inlet opening features area of 0.6-0.7 S(where Sis engine cross-section area), internal curved duct features length of 1-2 D, (where Dis engine diameter). Air intake inlet chute has a slot to discharge incident flow boundary layer.EFFECT: stable operation, compact design.3 dwg |
