throttleable

The engine was not throttleable but each chamber could be turned on and off individually.

The descent engine would become the first throttleable rocket engine fired in space.

A requirement for a throttleable engine was new for manned spacecraft.

Due to the need for a soft landing on the Moon, it was the first throttleable engine for manned space flight.

The RS-27A main engine is neither restartable nor throttleable.

The rocket is not throttleable.

The XLR99 engine was the first large, throttleable, restartable liquid propellant rocket engine.

Unlike solid rockets, Dream Chaser's hybrid fuel system would allow the motor to stop and start repeatedly, and be throttleable.

To assist in pre-landing flare, four throttleable hydrogen peroxide rockets provided up to 400 lbf (1.8 kN) of thrust.

(Many people have experienced throttleable pintle sprayers in the form of standard garden hose-end sprayers.)

The key to Meteor's performance is a throttleable ducted rocket (ramjet) manufactured by Bayern-Chemie of Germany.

The use of the pintle injector allows the engine thrust to be widely throttleable, as was the case for the Lunar Module Descent Engine.

In a throttleable ducted rocket, also known as a variable flow ducted rocket, a valve allows the gas generator exhaust to be throttled allowing control of the thrust.

The aircraft was powered by a Thiokol (Reaction Motors Division) XLR-99 throttleable rocket engine powered by anhydrous ammonia and liquid oxygen.

The propulsion sub-system (PSS) is a Throttleable Ducted Rocket (TDR) with an integrated nozzleless booster, designed and manufactured by Bayern-Chemie.

"It has a three-stage throttleable solid-rocket motor that gives it a range of over three hundred miles in a ballistic flight path or over one hundred miles in altitude in an antisatellite attack profile.

The engines had 18 nozzles to disperse the exhaust and minimize effects on the ground and were throttleable from 276 N to 2667 N. The hydrazine was purified to prevent contamination of the Martian surface.

Because the Reaction Motors Division of Thiokol Chemical Corp. did not have the throttleable XLR-99 engine ready for the early flights of the aircraft, the X-15 initially flew with two XLR-11 engines, producing a thrust of 16,380 lb.

Not only did the X-2 push the envelope of manned flight to speeds, altitudes and temperatures beyond any other aircraft at the time, it pioneered throttleable rocket motors (previously demonstrated on the Me 163B during World War II) and digital flight simulation.

The simple and reliable mission architecture was a pragmatic approach to solving the most critical space engineering challenges of the time, namely the closed-loop terminal descent guidance and control system, throttleable engines, and the radar systems required for determining the lander's altitude and velocity.
