1. Rotary Turbine (engine) Aeroplane Structure:

The rotary engine was an early variety of IC engine used in aviation normally designed with an odd number of cylinders each row in a circular arrangement, where the crankshaft is immobile in action, with the full crankcase and its connected cylinders rotating about it as one unit so that a steady firing sequence could be prolonged, to enhance smoother operation.

Nearly all of the rotary engines were presented with the cylinders directing away from a particular crankshaft, in the similar way as a radial engine. Rotary enignes provided power very smoothly as there were no reciprocating components, and the comparatively bigger rotating mass of the cylinder operated similar to a flywheel. Rotary engines had a basic unsuitable total-loss oiling technique.To achieve the whole engine lubrication the medium required to approach the crankcase from the hollow crankshaft, but the centrifugal force of the rotating crankcase was immediately incompatible to re-circulation. This was the basic on rotary turbine engine for aeroplane.

2. System of Helicopter and Aircraft:

The most regular aircraft is the fixed-wing aircraft. The wings on this type of aircraft are connected to the fuselage and are not supposed to move separately in a way that provides lift. The airframe of a fixed-wing aircraft is composed of five basic units: the fuselage, flight control surfaces, wings, stabilizers and landing gear. Helicopter airframes is composed of the fuselage, tail rotor, main rotor and gearbox, and the landing gear. Helicopters, have such huge maneuverability and very less landing speeds. A big amount of drag follows this type of gear, but an aircraft which cantake off and land on oceans can be very much required in certain conditions.

The construction of the helicopter are designed to provide the helicopter its individual flight features. The rotors are rotating airfoils which give lift same as that of wings which provide lift on a fixed-wing aircraft. Air flows rapidly over the upper surface of the rotors, generating a negative pressure and lifting the aircraft. Varying the angle of attack of the rotating blades enlarges or diminishes lift, accordingly raising or lowering the helicopter. Tilting the rotor plane of rotation forces the aircraft to progress horizontally
