Loads acting on the plane (1987)

The plane is on the runway, taking off.

Sunset, planes at the airfield.

The plane is being towed.

The pilot is in the cockpit at the controls, the dashboard.

View of the wing of the aircraft from the window.

View of the ground from the plane.

The plane is on the runway, taking off.

Np aircraft schematically shows how, under the influence of air flows, pressure arises on the upper and lower surfaces of the wing, how lift and drag force are created.

It is shown how the lifting force of the fuselage, stabilizer and controls arises.

It is shown when the moment of separation of the aircraft from the ground occurs.

The plane takes off.

A jet military plane takes off.

Vertical takeoff of the aircraft.

A pilot in a spacesuit.

The plane is in the air.

The plane schematically shows how the ratio of lift to gravity determines the transverse overload of the aircraft (the formula is derived).

It is shown how inertial forces increase with increasing overload.

The plane is in the air.

The calculation of the wing strength is schematically shown on the aircraft (the formula is derived).

Different types of aircraft in the air.

Calculated cases of aircraft loading.

Case D. Case A. Case D'.

Schematically it is shown how the calculated cases are determined.

Schematically it is shown how loads arise during the turns of the aircraft.

Panorama of the mountains.

Animated image - mountains, air masses, a plane is flying.

Schematically it is shown how the overload increases under the influence of the air flow.

Jet plane in the air.

Experiments, tests with an airplane model.

The plane turns around on the runway.

Schematically it is shown how, under the influence of loads on the aircraft, internal elastic forces, shearing force, bending and torques arise.

It is shown how the loads affect the calculation of the fuselage strength.

The plane is on the runway, taking off.

Schematically it is shown how the aircraft structure is deformed under the influence of various loads.

Animated image - the plane passes through zones in which there are ascending and descending air flows, it is shown how, as a consequence, the aircraft's flapping occurs.

The plane is in the air.

It is schematically shown how acoustic influences affect the design of the aircraft.

The plane is on the runway, taking off.

The plane's flutter.

Tests are carried out on a model aircraft.

The fast-growing self-oscillations of aircraft parts in the incoming air flow are shown.

It is schematically shown in which cases flutter occurs and what it can lead to.

Large - the landing gear of the aircraft.

The shimmy effect is the self-oscillation of the front wheel that occurs at a certain speed of the aircraft.

As a result of these fluctuations, there are vibrations of the wheel strut and deformation of the pneumatics.

The plane takes off, the landing gear is shown, the location installations are visible at the airfield.

The propulsion system of the aircraft.

The plane is in the air.

The plane is landing.

Schematically shows how the landing takes place and what factors affect the landing of the aircraft.

The plane is descending, landing.

Pilots in the cockpit, control the plane.

The plane is landing.

Planes on the territory of the airfield.
