Modern airplanes are well-prepared for slowing down, thanks to speed brakes and spoilers. There is actually a difference ...

However, the United States Air Force thinks the BWB concept could ... is reducing the wetted area and the associated drag. "Blended wing body aircraft provide numerous opportunities to address ...

Small, simple and 3D-printed fin-like structures, called microvanes and fitted onto aircraft to reduce drag and subsequently fuel consumption, will soon be rolled out on the U.S. Air Force’s C ...

The F-47’s illustrated features might have been intended as red herrings—or had their proportions exaggerated—all along. That ...

Despite these advantages, JetZero faces several serious obstacles in developing its blended wing aircraft. The most ...

The Northrop YF-23 “Black Widow II,” a prototype developed for the US Air Force’s Advanced Tactical Fighter competition in ...

to calculate the effect of the drag force. OK, we are going to need some more parameters. Along with the glide ratio, I'm going to use an aircraft mass of 80,000 kilograms and a cruising speed of ...

This causes some drag and turbulence problems even with ... vanes are installed on USAF and Air National Guard and Air Force Reserve aircraft, the project will pay for itself in seven months ...

shock waves form around the aircraft. These shock waves significantly increase the aerodynamic drag, and so more fuel needs to be burned to compensate for the drag force. Indeed, it is estimated ...

Their findings could lead to more efficient aircraft and boats with greatly ... There is also friction drag arising from the shear force between the fluid medium and a moving object's surface.
