How do coaxial rotors compensate for dissymmetry of lift?
How do coaxial rotors compensate for dissymmetry of lift? Dissymmetry of lift is an aerodynamic phenomenon caused by the rotation of a helicopter’s rotors in forward flight. Coaxial rotors avoid the effects of dissymmetry of lift through the use of two rotors turning in opposite directions, causing blades to advance on either side at the…
How do submarines detect enemy ships at sea?
How do submarines detect enemy ships at sea? Submarines themselves are equipped with passive sonar systems, such as towed arrays of hydrophones that are used to detect and determine the relative position of underwater acoustic sources. The SOund SUrveillance System (SOSUS) is a network of passive acoustic hydrophone arrays on the seafloor. How do anti-submarine…
