A numerical method based on the vortex methodology is presented in order to obtain unsteady solution of the aerodynamic coefficients of a thin airfoil in either compressible ... (Soviero and Ribeiro, ...

This design, known as transonic truss-braced wing (TTBW), could in theory allow the plane to generate more lift, thus reducing the amount of fuel it needs for certain portions of the flight.

The aircraft—being developed with a transonic truss-braced wing—is on “pause for later consideration” after Boeing proposed to focus on a ground-based testbed, which will instead ...

This airfoil has undergone extensive testing across various operational ... Additionally, investigations into drag-divergence behavior have been conducted using a transonic wind tunnel, with ...

“Transonic” tunnels (close to the speed of sound) are much more difficult. At this critical speed, very important in the study of aerodynamics, the tunnel tends to “choke.” Shock waves ...

1998) investigated a morphed airfoil, in which the radius of its leading edge was ... In a similar work focused on a transonic regime, reference (Tô et al., 2019) investigated the effects of upward ...

Our experimental results on the benchmark problems and a transonic airfoil design example show that the proposed algorithm is able to handle offline data-driven optimization problems with up to 100 ...

The usefulness of Shapley effects with PCE is then demonstrated and compared with total Sobol indices through a nonlinear test function and three engineering problems, including subsonic wing, ...

With the change, the partners started calling the design a “Transonic Truss-Braced Wing”. That is because, when flying at roughly M0.8, some air can accelerate around an aircraft’s airfoils ...

The dangers of the sound barrier were well-known: when airplanes approached the speed of sound, in the so-called "transonic" zone — pilots found they became hard to fly. Sometimes control could ...
