Propellant used in a sentence

Propellant in a sentence as a noun

Water doubles as a source of propellant. A human Mars trip may now only need to carry a one way load of propellant.

As the crew members make a toast drinking from their rocket propellant inspired cups the entire planet can be proud.

What's the alternative propellant? LH2 has all sorts of problems.

This gives us about 6 gallons of propellant for each pound of mass, for a cost of about $22. The fuel cost to launch something into orbit is about $22/lb.

Space junk is only a problem at higher orbits which can be stable for very long periods of time without propellant. As for 2...

The Falcon 9 upper stage didn't run out of propellant! It's that their ISS safety window didn't permit refiring.

It picked up a nasty roll though and centrifuged the propellant, cutting the engines prematurely. They recovered some debris but that's about it.

Parsons was one of the original founders of JPL. He was the team's chemist and developed the first castable solid propellant used to power aircraft."

For example, the descent stage energetically disassembled on impact with 100+ kg of unused propellant still on board, as planned [2]. Bits of plastic and metal are strewn across a 30km-long strip.

Muzzle velocity varies quite a lot based on ambient temperature, air pressure, altitude, and propellant grain size.

Propellant in a sentence as an adjective

This does add weight, for thermal protection and landing gear, and it uses up some propellant but on the whole the savings in capital and operational costs should more than make up for it. Right now the entire rocket is thrown away for every launch, which is hugely expensive.

- First use of the significantly longer first stage, which holds the additional propellant for the more powerful engines. - The nine Merlin 1D engines on the first stage are arranged in an octagonal pattern with eight engines in a circle and the ninth in the center.

The barrel would have to be three inches thick to contain the pressure, there'd be tons of propellant blowby as the barrel warped under pressure, it'd only work once, and the total lack of rifling would give you pathetic accuracy. It would "work", but be totally impractical, as well as expensive.

To be fair, the ATV is able to transfer propellant to the station which is something that only it and the Progress vehicles can do. For myself, I'm merely an enthusiastic amateur, I've been studying spaceflight closely since I was a child and I've come to pick up a few tidbits of trivia along the way.

With the propellant it carries, it can perform a velocity change of over 10 km/s, far more than any other spacecraft has done with onboard propellant after separation from the launch rocket." Voyager 2 got a 20km/s boost from Jupiter, and almost the same from Saturn, about 4km/s from Uranus, and about 10 from Neptune.

Both of those possible confounding factors are testable, either by measuring heat via IR imaging and computing what propellant effect that heat would have of by dummying up the null device to produce and dissipate an identical amount of energy to the non-null device. But honestly, I'm a hacker.

The propellant is intended to be kept at low pressure to minimise stress; a vehicle that is both large and light has an advantage during atmospheric reentry compared to other vehicles due to a low ballistic coefficient. [44] Because of the low ballistic coefficient, Skylon would be slowed at higher altitudes where the air is thinner.

Incidentally, the discovery of this method is sheer brilliance; without using gravity assists it would have taken prohibitively long and required a prohibitive amount of propellant to reach the outer planets.

Getting the astronauts back isn't prohibitively more difficult than getting them there in the first place: the energy expenditure for escaping the surface is 17% of the Earth's, and using the Mars Direct mission architecture, you can send a return vehicle ahead of time with seed hydrogen to manufacture liquid methane propellant and liquid oxygen oxidizer from the carbon dioxide air, through the Sabatier reaction for both and also with electrical dissociation of the carbon dioxide for more oxygen. You can also test it in flight after producing its fuel before deciding to launch the humans to Mars in the first place.
