Ridley had to rise to meet unexpected problems and new aerodynamic principles.

In 1934 the company introduced the Airflow models, featuring an advanced streamlined body, among the first to be designed using aerodynamic principles.

However, his sketchy design was interpreted with modern knowledge of aerodynamic principles, and whether his actual ideas would have flown is not known.

Unlike airplanes, which operate on aerodynamic principles, flying ships generate lift through powerful magnetic fields.

In my opinion, that aerodynamic principle offers our only chance of stable flight in such a turbulent sky as this one."

Air is not always the best test medium to study small-scale aerodynamic principles, due to the speed of the air flow and airfoil movement.

This was a comprehensive adoption of aerodynamic principles in a low-priced mass-produced post-war automobile.

All of these animals use the aerodynamic principles of flight, using the load-bearing properties of the wing.

Streamline was influenced by modern aerodynamic principles developed for aviation and ballistics to reduce air friction at high velocities.

It wasn't the kind of high-performance parachute he'd become accustomed to while jumping in Force Recon, but the aerodynamic principles were the same.

The reverse polarized turbulence of the quantum gravity field can really foul up the approach vector of the aerodynamic principle."

The aerodynamic principles which rotate the rotor are equivalent to that in autogiros, and normal helicopters in autorotation.

The aerodynamic principles of the wind tunnel work equally on watercraft, except the water is more viscous and so sets greater forces on the object being tested.

This irregular and unstable stall behavior has been attributed to advanced aerodynamic principles that were not fully counteracted until the advent of electronic stability controls years later.

His gliders are designed using aerodynamic principles in the style of the White Wings series, they differ in construction, being of all-paper rather than paper-balsa laminate fuselage.

Unlike the old-fashioned Dutch windmill design, which relied mostly on the wind's force to push the blades into motion, modern turbines use more sophisticated aerodynamic principles to capture the wind's energy most effectively.

Now, researchers at the University of Cambridge in England say they have discovered how insects like bees pull their big bodies into the air with tiny wings in ways that defy conventional aerodynamic principles.

The prototype RW 3 Multoplan was designed by Hanno Fischer who founded Rhein-West-Flug Fischer in 1955 in order to test the aerodynamic principles that he propounded.

Using the same aerodynamic principles that enable a maple seed to waft to the ground, the shell can be fired by a conventional mortar and float harmlessly to the earth as it dispenses a nonlethal payload.

The ball has been named the "Projapoti" (in Bangla) or in English "Butterfly Ball" due to its erratic movement patterns through the air, and is based on the same aerodynamic principles as baseball's knuckleball.

After explaining the aerodynamic principles that are supposed to make Mr. Rahal's car work, "Fast Cars" chronicles his tribulations in trying to get it to go fast enough to qualify for the 1993 Indy 500 without its killing him.

It introduced entirely new aerodynamic principles to kiting which we shall describe under 'Foils' later, and because of its efficiency, it has been applied to power-kiting with some astonishing results, not least being measured speeds approaching 195km/h (120mph) in horizontal flight.

Basic aerodynamic principles dictate that the downforce created by air pressure on a surface increases exponentially with speed, thus, as with many aerodynamic modifications the bumper canards are primarily suited to the high speed conditions of motor racing.

The aerodynamic principles of an annular wing were basically sound, but the proposal was faced with a whole host of unsolved manufacture and control problems which would have made the project highly impractical even were it not for the materials shortages of late-war Germany.
