propellant mass वाक्य

उदाहरण वाक्य

1. For this reason the related term propellant mass fraction, is used instead.
2. Propellant mass fractions are typically around 0.8 to 0.9.
3. The total propellant mass at launch was.
4. A proton-antiproton annihilation propulsion system transforms 38 % of the propellant mass into an intense highenergy flux of gamma radiation.
5. The amount of propellant mass used measures the efficiency of the " maneuver plus the hardware " employed for it.
6. Future versions of the stage would increase the propellant mass to 100 tons ( P100 ) and 120 tons ( P120 ).
7. Thus, the engines and the control system was developed to ensure the simultaneous consumption of propellant mass among the four R-7 boosters.
8. The propellant mass fraction is the ratio of just the propellant to the entire mass of the vehicle at takeoff ( propellant plus dry mass ).
9. However, for reaching orbital speed, hydrogen is a better fuel, since the high exhaust velocity and hence lower propellant mass reduces the takeoff weight.
10. In other words, the "'propellant mass fraction "'is the ratio between the propellant mass and the initial mass of the vehicle.
