Abstract

The invention provides a flying-wing and forward-swept-wing joint-wing aircraft. Thin airfoil columns A and B are added at 70% of the wingspan on both sides of the rear-swept-wing flying-wing aircraft, and at the tail of the flying-wing aircraft A thin airfoil column C is added, and a horizontal forward swept wing is added to the top of the three thin airfoil columns A, B and C to form a flying wing and a forward swept wing joint wing layout. The elevator is mounted on the horizontally swept wing, and the rudder is mounted on the column C. A ducted air intake is used on the upper airfoil of the flying wing, and cracked resistance rudders are arranged at the thin airfoil columns A and B. Under the condition of effectively ensuring the structural strength, the present invention increases the effective aspect ratio of the wing, reduces the induced resistance, improves the lift-drag characteristics of the aircraft, improves the stealth performance of the aircraft, and realizes direct and direct control of the aircraft in the vertical direction. Force control improves detection accuracy under maneuvering conditions.

Description

technical field

[0001] The invention belongs to the field of a novel aircraft involving a novel shape design and aerodynamic characteristics, in particular a novel aircraft layout utilizing a combination of a flying wing layout and a forward-swept wing. Background technique

[0002] At present, most commercial aircraft have a conventional single-wing cylindrical fuselage layout. The military is trying and has successfully used the flying wing layout to form a good stealth effect. However, the traditional flying wing uses a swept wing, and its stall first occurs at the wingtip. , causing the center of lift to move forward and the nose to rise, further deepening the stall. The aerodynamic lift effect of the aircraft with flying wing layout is not good during flight, which greatly restricts its maneuverability and flight speed during flight, which is not conducive to high-altitude and long-endurance flight, and fuel waste occurs. However, the current forward-swept wing aircraf...
