| You don't want an arm sticking out when you go from transonic to supersonic. |
|
| Aerodynamic forces cause vibrations at the tip of a blade where the effects of transonic speeds cause buffeting and vibration. |
|
| It is primarily intended to benefit aircraft that operate in the transonic speed range. |
|
| The extreme constraints on the structure are observed at the beginning and the transonic flight. |
|
| This major facility is a pressurized, intermittent flow wind tunnel capable of running in the subsonic, transonic and supersonic flow regimes. |
|
| When a bullet in free flight is in transonic velocity range both above and below the speed of sound, it's subject to forces detrimental to accuracy. |
|
| It is, however, quite inefficient at transonic flight speeds and is completely ineffective at subsonic velocities. |
|
| Activities are concentrated on determining flutter boundaries of complex aircraft configurations for subsonic, transonic and supersonic regimes. |
|
| Scientific: i.e. aerodynamic characteristics of the transonic flow in a rarefied atmosphere for a human in free fall. |
|
| At the beginning and during the initial phase of the flight the vibrations are generated by the engines of Energia, but it is at the time of the descent, which is accompanied transonic speeds, that the levels are maxima. |
|
| Operating in the subsonic, transonic and supersonic flow regimes at speeds ranging from Mach 0.1 to over Mach 4, the pressurized, intermittent flow facility provides an ideal venue for testing models under various conditions. |
|
| Wings were made thinner and swept back to reduce transonic drag, which required new manufacturing methods to obtain sufficient strength. |
|
| The topics covered include applications such as supersonic intakes and nozzles, oblique shock waves and their reflections, airfoil and fuselage designs for transonic flight. |
|
| The inlet system's job for transonic and supersonic aircraft is to slow the air and perform some of the compression. |
|
| Supersonic flight offered the aeronautical engineer new challenges in propulsion, structures and materials, high-speed aeroelasticity, and transonic, supersonic, and hypersonic aerodynamics. |
|
| The solution involved adding volume to the fuselage ahead of and behind the wing and reducing it near the wing and tail, to create a cross-sectional area that more nearly approximated the ideal area to limit transonic drag. |
|
| These fighters operated at high subsonic speeds, but the competitive pressures of development required aircraft that could operate at transonic and supersonic speeds. |
|
| For high subsonic and transonic flow regimes, a separate test section with perforated walls is contained within a pressure-tight plenum chamber and minimizes the impact of shock reflections and blockage. |
|
| As per information, the M-346 is a transonic aircraft which is developed by the company in association with Russia's Yakovlev. |
|
| Following the conversation with his father, Jason realised that he could conduct the tests of the vehicle for the transonic phase. |
|
|
|
| The exhibition marks a new era for the wind tunnels which were originally used for speed and transonic testing of aircraft. |
|
| Clearly, the aerodynamic challenges associated with developing a land-based vehicle capable of safely travelling at transonic speeds are great. |
|
| In all that time, I believed that keeping velocity under the transonic region was crucial for the best accuracy. |
|
| Techniques for implanting a chronic hepatic portal vein transonic flow meter and catheters in the hepatic portal vein, ileal mesenteric vein and carotid artery in swine. |
|
| He has patents on wing and airfoil design concepts for efficient transonic transports, powered high-lift concepts, and short takeoff and landing configurations. |
|
| At transonic speeds, near the speed of sound, it helps to sweep the wing backward or forwards to reduce drag from supersonic shock waves as they begin to form. |
|
| Testing began last week at Boeing's Transonic Wind Tunnel in Seattle. |
|
| The Acid Mothers collective was formed five years ago by Kawabata Makoto, whose previous outfits have included Musica Transonic, Mainliner and Toho Sara. |
