| 1. | They are also much more fuel-efficient at normal flight speeds than rockets.
|
| 2. | Monarch flight speed has been estimated by a number of researchers.
|
| 3. | No longer was revolutionary progress made in flight speeds, distances and materials technology.
|
| 4. | During the 1960s the wing established world flight speed records in the B-58.
|
| 5. | Consequently, nozzle gross thrust initially only increases marginally with flight speed.
|
| 6. | At a lower cruise flight speed ( e . g.
|
| 7. | The flying reptile soon emerges, but his flight speed has been cut by half.
|
| 8. | The high flight speed allows it to engage targets rapidly.
|
| 9. | So, for instance, raising intake stagnation temperature by increasing flight speed, at a constant "'
|
| 10. | Outside a planetary atmosphere his flight speed can even reach near the speed of light.
