A ramjet generates no static thrust and needs a booster to achieve a forward velocity high enough for efficient operation of the intake system.
12.
:: I don't think the planets would be pushed progressively out of orbit, since their forward velocity would not be sufficient to maintain an orbit further out.
13.
A torque M applied on the axle causes creepage : difference between forward velocity V and circumferential velocity \ omega R, with resulting creep force F _ w.
14.
Late on September 20, this set-up caused the storm's forward speed to increase substantially, ultimately reaching 70 mph, the highest forward velocity ever recorded in the annals of hurricanes.
15.
The circulation around a conventional airfoil, and hence the lift it generates, is dictated by both its design and the flight conditions, such as forward velocity and angle of attack.
16.
They applied full power to this engine, which caused the craft to enter a circling descent until crashing into trees; at the time of impact it had almost no forward velocity.
17.
You have to make sure you have enough forward velocity and make yourself small and roll when you hit the ground . talk ) 01 : 09, 26 October 2010 ( UTC)
18.
The main parameter for achieving stable transonic transition is controlling the drag coefficients ( C d ) and forward velocity loss around Mach 1 and to a lesser degree controlling the spin deceleration.
19.
Some of the required crash data include pre-crash speed, engine throttle, brake use, measured changes in forward velocity ( Delta-V ), driver safety belt use, airbag warning lamp status and airbag deployment times.
20.
As the forward velocity increases, the wings produce greater amounts of lift . At a high enough speed, the lift force will exceed the weight of the aircraft, and the aircraft will become capable of sustained flight.
