Every comercial aircraft must be able to be evacuated, in medium density configuration,within 90 seconds, using only 50% of the doors. In order to measure the time, the passengers are a representative sample of population without any preparation.

Every comercial aircraft must be able to be evacuated, in maximum density configuration,within 90 seconds, using only 50% of the doors. In order to measure the time, the passengers are a representative sample of population without any preparation.

Every comercial aircraft must be able to be evacuated, in medium density configuration, in more than 90 seconds, using only 75% of the doors. In order to measure the time, the passengers are a representative sample of population without any preparation.

Structural elements to share the load

Semi-Monocoque is used in missiles

Monocoque is only for wings

Semi-monocoque is only for fuselage

Because it is stylish

In order to increase the windows resistance

thin-film gold is needed for the airplane’s anti-fog system

It reduces the radar signature

They are span-wise elements to support the skin and increase the rigidity to compression.

They are attached to formers in the wing.

They are support the main loads of the wing performance.

They are used only in military aircraft

buckling effect

Coanda effect

Traction forces

Torsion forces

In the same direction as the aerodynamic chord

Perpendicular to the aerodynamic chord

Oblique to the aerodynamic chord

Ribs are not located in the wing but in the fuselage.

It is the external part of the structure, which mission is to resist shear and isolate the fuel from the atmosphere.

It is a lift device attached to the fuselage

It is the internal part of the structure, which mission is to resist shear and isolate the fuel from the atmosphere.

It is the external part of the window, which mission is to resist shear and avoid hits on the window surface.

Block pilot’s visibility in a turn

Wing can be manufactured in only 1 section

The center wing structure is used for the cabin flood and to accommodate the landing gear without aerodynamic penalty

Structural carrythrough

Central Box.

Formerons

1,3

1,2

1,2,4

2,3,4

Reduced forward and down visibility

Higher landing and take off speeds

Lower maneuverability

May be prone to suffering a dangerous deep stall condition

Aerobatic maneuverability

Prevent "floating" (ground effect) that complicates the landing and the placement of motors allow landing in unimproved fields

Delay the critical Mach

The center wing structure is used for the cabin floor and to accommodate the landing gear without aerodynamic penalti
