Aircraft comprising a cockpit delocalized outside an upper part of the nose

Abstract

The invention concerns an aircraft comprising a fuselage, a cockpit (10) and a cabin (11), characterized in that the cockpit (10) is situated below the cabin (11), outside the nose of the aircraft. the cabin (11) advantageously extends to a front end of the aircraft. Preferably, the aircraft has a lancet-shaped nose.

Description

technical field [0001] The invention relates to a cockpit for a civil transport aircraft, ie a commercial aircraft for transporting passengers, their luggage and / or merchandise. The cockpit, commonly called the cockpit, is the space dedicated to the pilot. The cockpit houses all the controls (rudder and other flap actuation controls, landing gear, engines, speedbrake actuation controls, etc.) and instruments needed to fly the aircraft. Background technique [0002] For many years, the construction of the aircraft, in particular with regard to the position of the cockpit in the aircraft, has been fixed. In order to give the pilot good visibility of the external scene in front of the aircraft, the cockpit has traditionally always been located in the front of the Glass windows to provide the pilot with a wide view towards the front of the aircraft and also a wide view downwards for the take-off and landing and ground taxiing phases. Throughout the following, "nose" is to be ...

AI Technical Summary

Problems solved by technology

But housing the radar, the landing gear and especially the cockpit in this nose makes it necessary to provide a much more complex shape and structure with various radii of curvature

More specifically, the presence of a cockpit requires the provision of a canopy with a large area to give physical operational visibility and to respond to certification requirements and regulations, the canopy being a heavy glass surface requiring the installation of multiple structural reinforcements, Structural reinforcements further increase the mass of the aircraft and make the nose one of the most complex parts of the aircraft to implement

[0004] In order to optimize the external view and more specifically to limit the problem of optical distortion and limit the impact on the aerodynamics of the aircraft, the known canopy preferably comprises a frontal glazing either flat or with two large-radius curvatures, which is essential for The glass part further increases the weight

The known canopy is a complex part to implement, which is difficult to integrate into the ideal aerodynamic shape of the aircraft, also due to the shape discontinuities and the structural resistance caused by these shape discontinuities (the canopy is "non-working ” surface) while weakening the nose

[0005] Furthermore, the positioning of the cockpit at the front of the aircraft in the cabin extension also reduces the size of the cabin and reduces the number of passengers that can be accommodated or reduces passenger comfort, thereby limiting the financial profitability of the airline operating the aircraft
