| Somehow, he managed to come out of the spin and slow his speed to from hypersonic to subsonic. |
|
| The windowpanes rattled, and the girls could feel the subsonic boom of a bomb exploding. |
|
| The small, winged AGM-86B is powered by a turbofan jet engine that propels it at sustained subsonic speeds. |
|
| The students also tailored the shape and proportions of their blade to keep the airflow subsonic. |
|
| The Tomahawk is a long-range subsonic cruise missile that is launched from ships and submarines. |
|
| The missile uses command updated inertial guidance and reaches high subsonic speed, 0.9 Mach. |
|
| This major facility is a pressurized, intermittent flow wind tunnel capable of running in the subsonic, transonic and supersonic flow regimes. |
|
| Caution: To avoid subsonic noise, soldering must take place according to this scheme. |
|
| The ONE-HIDE-STAND-2 and the ONE-HIDE-STAND-3 both have a robust but slim cast base and an integrated rubber mat that dampens subsonic noises. |
|
| One type, called a ramjet, slows incoming air to subsonic speeds using a carefully shaped inlet to compress and thereby slow the airstream. |
|
| For this reason, all match ammunition is subsonic to reduce wind drift. |
|
| The 2 m x 3 m wind tunnel is a world-class facility for subsonic aeronautical and industrial testing. |
|
| The company designs, manufactures and distributes a full range of machine guns, mounts, pods and rocket launchers to equip multi-role helicopters and subsonic aircraft. |
|
| However, with the reduction of subsonic flights within the LLTA, the need to focus on river dwelling species is not considered a priority. |
|
| Supersonic aircraft consume more than twice the fuel per passenger-km compared to subsonic aircraft. |
|
| To improve the aircraft's longitudinal stability, and to avert stall at steep angles and subsonic speed, there are two shallow upper-surface fences on each wing. |
|
| The drag of a subsonic plane is primarily due to friction with the air, as well as the pressure difference between the front and trailing surfaces. |
|
| Once the vehicle returns to the lower atmosphere and drops to subsonic speeds, the jet engines will reignite for a powered landing back at the spaceport. |
|
| The plane, with three pilots and a number of other cabin crew, then turned round and headed back to Heathrow, flying at subsonic speed and landing safely at 2.06 pm. |
|
| Number of allowable conditions for inviscid and viscous subsonic flow in an open domain. |
|
|
|
| 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. |
|
| The supersonic incoming air is dramatically slowed through the inlet, where it is then combusted at the much slower, subsonic, speeds. |
|
| Indeed, the winged devices possess a higher aerodynamic quality in the hypersonic and subsonic flight which allows to limit loads on the crew during the descent in the atmosphere. |
|
| But he has now developed a way to do so. As the supersonically flowing condensate slows down it creates a second boundary at the point where its velocity becomes subsonic. |
|
| Indeed, notes Mr Tracy, the market is big enough that Gulfstream has developed long-range subsonic aircraft to service it, so there should be room for supersonics too. Nor is Aerion alone in this belief. |
|
| These fighters operated at high subsonic speeds, but the competitive pressures of development required aircraft that could operate at transonic and supersonic speeds. |
|
| 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. |
|
| 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. |
|
| The Commission has decided to prosecute Belgium before the Court of Justice for infringing the Community provisions on the limitation of noise emissions from subsonic aircraft. |
|
| The Commission has decided to initiate proceedings against Belgium for infringement of Community rules on the limitation of noise from subsonic aircraft. |
|
| Early jet aircraft used turbojet engines which were relatively inefficient for subsonic flight. |
|
| Turbofans are usually more efficient than turbojets at subsonic speeds, but their large frontal area also generates more drag. |
|
| A key trait of ramjet engines is that combustion is done at subsonic speeds. |
|
| The faster the incoming air is, however, the less efficient it becomes to slow it to subsonic speeds. |
|
| In the subsonic case the noise is produced by eddies and in the supersonic case by Mach waves. |
|
| At the front of the engine, a simple translating axisymmetric shock cone inlet slows the air to subsonic speeds using two shock reflections. |
|
| Some zoologists hypothesise that some animal species have an ability to sense subsonic Rayleigh waves from an earthquake or a tsunami. |
|
| The noise of the ship was all around her. The faint subsonic rumble of the reactor and drive. |
|
| Boeing's hypersonic, supersonic, subsonic and icing wind tunnels in Seattle and Philadelphia will remain open during the renovations. |
|
|
|
| Professor French and his students wanted to develop a demonstration of how a de Laval nozzle converts subsonic gas flow into supersonic flow. |
|
| Later upgrades will include the Phazotron Zhuk-AE Aesa radar, the 200-km Novator K-100 air-air missile, and the 750-km nuclear-capable DRDO Nirbhay subsonic cruise missile. |
|
| The Sabre began life as a straight-wing design which was produced as the FJ-1 Fury, a tubby airplane of clearly subsonic planform and performance. |
|
| Among specific topics are buoyancy and stability, basic elastostatics, nearly ideal flow, action and reaction, gravity waves, and subsonic flight. |
|
| Subsonic explosions are created by low explosives through a slower burning process known as deflagration. |
