A series of experiments using paper airplanes reveals new aerodynamic effects, a team of scientists has discovered. Its findings enhance our understanding of flight stability and could inspire new types of flying robots and small drones. "The study started with simple curiosity about what makes a g...
The design of Micro Air Vehicles (MAV) is challenging since the aerodynamic efficiency of airfoils and wings decreases at low Reynolds-numbers. While many MAV approaches investigate biological designs, we present an investigation on the aerodynamics of paper airplanes, which fly in the same Reynolds...
Presented in the paper are results of studies on aerodynamics of short takeoff and landing (STOL) transport aircraft with various types of powered lift systems (PLS), performed at the Central Aerohydrodynamic Institute (TsAGI), named after Prof. N.E. Zhukovsky.The test results obtained in the...
Intense wingtip vortices, which are similar to tornados, are strong enough to flip airplanes that get too close. Adding winglets helps to lower the required amount of spacing between planes at the airport and making flying more efficient. They also reduce drag, improving takeoff time, and-when...
Because the rack drags in the air and slows you down. Forairplanesandspace rockets, aerodynamics is even more important. When spacecraft return to Earth, they pass from the virtual vacuum of space into Earth's atmosphere at high speed, which heats them up dangerously; in February 2003, the...
Modeling high-dimensional aerodynamic data presents a significant challenge in aero-loads prediction, aerodynamic shape optimization, flight control, and simulation. This article develops a machine learning approach based on a convolutional neural networ
Study of belly-flaps to enhance lift and pitching moment coefficient of a Blended-Wing-Body airplane in landing and takeoff configuration During the first century of flight few major changes have been made to the configuration of subsonic airplanes. A distinct fuselage with wings, a tail, eng.....
