1. Drag loss of vehicles like aircraft or ships generally increases less than proportional with increasing cargo volume, although the physical details can be quite complicated.
2. Comper was an early adopter of retractable undercarriages for light aircraft at a time when the balance of advantage between drag loss and weight penalty was not obvious.
3. Hydrogen has very low viscosity, a favorable property for reducing drag losses in the rotor; these losses can be significant, as the rotors have large diameter and high rotational speed.
4. However, a shorter bell shape is typically used, which gives better overall performance due to its much lower weight, shorter length, lower drag losses, and only very marginally lower exhaust speed.
5. The 40 megajoules per kilogram or less kinetic energy of projectiles launched at up to 9000 m / s velocity ( if including extra for drag losses ) towards Low Earth Orbit is a few kilowatt-hours per kilogram if efficiencies are relatively high, which accordingly has been hypothesized to be under $ 1 of electrical energy cost per kilogram shipped to LEO, though total costs would be far more than electricity alone.
6. It's difficult to find drag losses in a sentence. 用drag losses造句挺難的
