Webb12 sep. 2024 · The most fuel-efficient cruising speed is about 70–80 km/h (about 45–50 mi/h). For this reason, during the 1970s oil crisis in the United States, maximum speeds on highways were set at about 90 km/h (55 mi/h). Table 6.7.1: Typical Values of Drag Coefficient C. Object. WebbFins should be rounded and not have sharp edges. Also, they should be thin as they are just helping the rocket fly straight. If fins are thicker, they expose more surface area perpendicular to the direction of travel which creates more drag. Also, the fins should be swept towards the bottom of the rocket, which again helps to reduce drag.
