they dive and use their wings for propulsion under water.

A four-joint flexible underwater pisciform propulsion system is developed and the control flow chart is presented.

2 Class B: AIRSHIP or DIRIGIBLE -An aerostat, equipped with means of propulsion and steering.

Preliminary analysis shows that the propulsion force is relative to serval factors, such as liquid viscousness, drive fin wet area and offset, etc.

The predevelopment phase for the injector of a new 27.5kN engine, which will be used in the Ariane 5 upper stage and the Hermes spaceplane propulsion module, has been completed.

In addition, the USAF continues to fund development work of the Aerojet (formerly Atlantic Research) Variable Flow Ducted Rocket ramjet system as a future propulsion option for an extended range AAM.

We'd have to design new propulsion, navigation, hibernation and life support systems.

A firecracker is a rocket because it has a propulsion system.

The submarine's nuclear propulsion system is said to be unaffected.

And hopefully we'll have new kinds of propulsion coming along as well.

The first electric propulsion engines were actually developed in the 50s and 60s.

We currently have nuclear propulsion systems.

The technological conscience of this effort is the jet propulsion laboratory's chief engineer, Gentry Lee.

Why was she not allowed into the engineers' lectures on orbital mechanics and rocket propulsion?

The Pacific flying squid uses jet propulsion for another purpose: to launch itself right out of the water.

SCOTT MORRISON, PRIME MINISTER OF AUSTRALIA: To stress again, this is about propulsion.
