Jet pipe arrangement for aircraft propulsion and control

Abstract

A jet pipe arrangement is provided for the propulsion and control of an aircraft, which arrangement includes a first stationary pipe section which has a second pipe section fitted with a thrust nozzle attached thereto. To facilitate a simply constructed and operated control arrangement for rotatably moving the second pipe section with respect to the first pipe section, two pairs of angle levers are disposed about the circumference of the first pipe section. The first pair of angle levers are located opposite one another on the first pipe section and have pivot fulcrums located in the plane parallel to the vertical pivot axis of the second pipe section. The second pair of angle levers are likewise located at respective opposite sides on the circumference of the first pipe section and include pivot fulcrums located in a plane parallel to the horizontal pivot axis of the second pipe section. With this arrangement of the angle levers, it is possible to selectively pivot the second pipe section about either or both of the horizontal and vertical pivot axes. To accommodate shifting of the effective rotational or pivot axes of the second pipe section, compensating linkages are also provided between the angle levers and the respective pipe sections.
