查询词典 rocket

The results showed that the performance of unchoked ducted rocket is superior to that of choked one. When the gas generator is loaded with high burning-rate exponent fuel-rich propellant, the performance of unchoked ducted rocket is almost the same as that of the ducted rocket working under fixed mass ratio of fuel to air.
