Abstract: Drag reduction systems and methods for an aircraft include a first vortex generator position on a portion of the aircraft, and a second vortex generator positioned on the portion of the aircraft. The first vortex generator is associated with the second vortex generator. The first vortex generator is asymmetrical to the second vortex generator in relation to a coupling axis in order to offset the longitudinal contribution of the vortex generator to vehicle cross-sectional area.

Abstract: This disclosure is directed to increasing the use of protective eyewear in safety-critical environments. Systems and methods disclosed herein include lighting devices that emit ambient lighting and safety lighting for an environment. The safety lighting includes visible characteristics different from the ambient lighting. Additionally, the systems and methods include protective eyewear having a lens that filters out substantially the visible characteristics of the safety lighting striking the lens and pass components of the ambient light safety lighting striking the lens.

Abstract: An air vehicle may include a body having forwardly-swept fixed wings or unswept fixed wings. The body may have a longitudinal axis continuously oriented parallel to a forward flight direction when the air vehicle is in flight. The air vehicle may include at least one of the following components being mounted on opposite sides of the body: longitudinally offset engine nacelles, asymmetrically lengthened engine nacelles, and longitudinally offset protruding aerodynamic surfaces comprising at least one of stabilizers, canards, empennage control surfaces, external stores, and high aspect ratio wings.

Abstract: An air vehicle having a bilaterally asymmetric configuration for reducing wave drag may include a body having a longitudinal axis. The air vehicle may further include longitudinally offset engine nacelles, asymmetrically lengthened engine nacelles, and/or longitudinally offset protruding aerodynamic surfaces for reducing wave drag.
