Ducted fans are favored in VTOL aircraft such as the Lockheed Martin F-35 Lightning II, and other low-speed designs such as hovercraft for their higher thrust-to-weight ratio.
In some cases, a shrouded rotor can be 94% more efficient than an open rotor. The improved performance is mainly because the outward flow is less contracted and thus carries more kinetic energy.
Among model aircraft hobbyists, the ducted fan is popular with builders of high-performance radio controlled model aircraft. Internal-combustion glow engines combined with ducted-fan units were the first achievable means of modeling a scaled-size jet aircraft. Despite the introduction of model-scale turbojet engines, electric-powered ducted fans remain popular on smaller, lower-cost model aircraft. Some electric-powered ducted fan airplanes can reach speeds of more than 320km/h (200mph).
Germany comprises sixteen federal states which are collectively referred to as Bundesländer. Each state has its own state constitution, and is largely autonomous in regard to its internal organisation. Two of the states are city-states consisting of just one city: the national capital of Berlin, and Hamburg. The state of Bremen consists of two cities that are separated from each other by the state of Lower Saxony: Bremen and Bremerhaven.
Because of the differences in size and population, the subdivisions of the states vary. For regional administrative purposes four states, namely Baden-Württemberg, Bavaria, Hesse and North Rhine-Westphalia, consist of a total of 19 Government Districts (Regierungsbezirke).
