As observed in Section 3.1 for equilibrium in hover, the system in Equation (11) is complemented by the three definitions in Equation (10) (which hold also when substituting symbol 𝑇𝑖Ti with Δ𝑇𝑖ΔTi everywhere in the latter). The resulting linear system of equations may be solved...
An official logo for Finland’s Air Force that prominently featured a swastika is no more. The Nordic country’s military branch, which had been using the symbol decades before it became linked to Nazi Germany that ravaged Europe during World War II, has quietly changed a unit emblem to now...
