Protection panel and landing gear module comprising it
The invention relates to a protection panel ( 115 ) for a vehicle that comprises an outer surface ( 140 ) including at least one composite material, and is mounted via deformable parts on a mounting ( 135 ) attached to the vehicle structure. The deformable parts are attached to several stiffening parts ( 145 ) of the mounting. In some embodiments, the deformable parts are perpendicular to the outer surface of the panel and are capable of buckling under the effect of impacts. In some embodiments, the deformable parts are in the form of clips, the composite material consists of CFRP and the mounting is rigid.
1. A protective panel on a landing gear module on an aircraft, comprising:
a panel body having an outer surface including at least one composite material, the outer surface being exposed to an outside of the aircraft;
a support forming a structure of the protective panel, the support being linked to a structure of the aircraft, and the support including a plurality of stiffening parts; and
a plurality of deformable parts that mount the panel body to the support, the plurality of deformable parts being attached to one or more stiffening parts of the support,
wherein a deformation rate of the plurality of deformable parts is correlated with a coefficient of breaking elongation of the outer surface so that, when the protective panel is impacted, the deformable parts become deformed before the outer surface breaks,
wherein the deformable parts are disposed such that a height direction of extension of the deformable parts is oriented to extend perpendicular to the outer surface of the panel body, and
wherein the deformable parts are configured to buckle under the effect of impacts.
2. The protective panel according to claim 1 , wherein the deformable parts are clips.
3. The protective panel according to any one of claim 1 or 2 , wherein the deformable parts are attached to several stiffening parts of the plurality of stiffening parts, which are frames.
4. The protective panel according to claim 3 , wherein the deformable parts are attached to several stringers supported by the frames.
5. The protective panel according to claim 1 , wherein the composite material of the outer surface is made of carbon fiber reinforced plastic.
6. The protective panel according to claim 1 , wherein the support is rigid.
7. A landing gear module, comprising: a landing gear; and a protective panel according to claim 1 .
8. An aircraft, comprising at least one landing gear module according to claim 7 .
9. The protective panel according to claim 2 , wherein the clips are longitudinally extending brackets having a first arm portion that extends at approximately a right angle away from a second arm portion, the first arm portion being longer than the second arm portion, and wherein the second arm portion is mounted to the panel body such that the first arm portion extends substantially perpendicularly to the outer surface of the panel body.
10. The protective panel according to claim 1 , wherein the plurality of deformable parts mounts the panel body to the support such that the deformable parts are disposed between the panel body and the stiffening parts.
