A model of the Transonic Truss-Braced Wing aircraft in a wind tunnel at NASA's Ames Research Center. By early 2019, following extensive wind tunnel testing at NASA Ames Research Center, an optimized truss and more sweep for the 170 ft (52 m) span wing allowed flying higher and faster, up from Mach 0.70–0.75 to Mach 0.80 like current jetliners.

Illustration of the Boeing SUGAR Volt concept aircraft. SUGAR Volt is the hybrid aircraft concept proposed by a team led by Boeing's Research & Technology division. It is one of a series of concepts put forward in response to a request for proposals for future aircraft issued by NASA.
Typically, the ends of bracing struts are joined to the main internal structural components such as a wing spar or a fuselage bulkhead, and bracing wires are attached close by. Bracing may be used to resist all the various forces which occur in an airframe, including lift, weight, drag and twisting or torsion.
It’s called the Transonic Truss-Braced Wing concept, which relies on elongated, thin wings stabilized by diagonal struts that connect the wings to the aircraft. The design’s shape creates less ...
A major push has been made toward additive manufacturing techniques due to a decrease in overall material and production costs and high efficiency and accuracy while providing control over parameters like porosity. Also, the ease of prototype manufacturing for testing purposes has made a huge contribution.
Supercritical airfoils feature four main benefits: they have a higher drag-divergence Mach number, [21] they develop shock waves farther aft than traditional airfoils, [22] they greatly reduce shock-induced boundary layer separation, and their geometry allows more efficient wing design (e.g., a thicker wing and/or reduced wing sweep, each of which may allow a lighter wing).
Design for additive manufacturing (DfAM or DFAM) is design for manufacturability as applied to additive manufacturing (AM). It is a general type of design methods or tools whereby functional performance and/or other key product life-cycle considerations such as manufacturability, reliability, and cost can be optimized subjected to the capabilities of additive manufacturing technologies.
