A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high speeds with relatively little power—up to 6,–8, km/h (4,–5, mph).This is 5–6 times the speed of sound in Earth's atmosphere at.

flowfield, getting stronger as the speed increases. The shock waves lead to a rapid increase in drag, both due to the emergence of wave drag, and also because the pressure rise through a shock wave thickens the boundary layer, leading to increased viscous drag. Thus cruise speed is limited by the rapid drag Size: 2MB. On the Aerodynamic Design of the Hyperloop Concept Max M. J. Opgenoord⇤ and Philip C.

M. Hirst, in Innovation in Aeronautics, Aerodynamics. The over-riding concern in the design of an airliner is to achieve a high lift-to-drag ratio (L/D) in sely, if a ludicrously low-cost energy source is found, such that the vehicle drag can be overcome by thrust obtained at virtually no cost, the logicality of this requirement is overturned.

Traditionally, aerial bombs have been squat, cylindrical, with a blunt nose. Such bombs are called "high drag" because they have a dramatic effect on a fighter-bomber when carried under the wings.
