Abstract: An aircraft (1) with jettison mechanism, particularly a helicopter, comprising an airframe (2), at least one door (5) movably mounted to the airframe (2), at least one door lock mechanism (9) at an interface of said at least one door (5) with the airframe (2) to releasable mount the at least one door (5) relative to the airframe (2) and actuation means (11) for the at least one door lock mechanism (9). An emergency jettison button (20, 38) is integrated into handles (11, 12) of said actuation means.

Abstract: A display element for an electronic module configured as an optical waveguide arrangement is provided. The display element includes a first optical waveguide part with a first light-receiving surface and a first light-emitting surface. The display element further includes a second optical waveguide part with a second light-receiving surface and a second light-emitting surface. The first optical waveguide part and the second optical waveguide part are arranged opposite one another. A first guide is arranged on an inner side of the first optical waveguide part and a second guide is arranged on an inner side of the second optical waveguide part. The respective inner sides are arranged in relation to one another such that the designation label is configured to be fastened by the first and second guide.

Abstract: The invention relates to a skid-type landing gear (1) for a helicopter (2) comprising bow shaped crosstubes (10-13) directed symmetrically towards a left- and a right-hand side of a longitudinal mid axis (9) of the helicopter (2) with respective skids (14, 15) at outboard ends thereof and main beams (5-8) in a fuselage (4), the crosstubes (10-13) being connected to the main beams (5-8) via supports (16-23) fixed to the main beams (5-8). The skid-type landing gear (1) is retractable. A method for operating such a skid-type landing gear (1) for a helicopter (2) is provided.

Abstract: A helicopter with a fuselage and a skid-type landing gear mounted to said fuselage. Said landing gear comprises pivotable cross beams and skids, said skids being each disposed in an essentially longitudinal direction laterally on a respective side of the helicopter's landing gear. At least one discrete damper is provided for at least one pivotable cross beam, said discrete damper being connected with one end to the pivotable cross beam and with another end to the fuselage. The pivotable cross beam are of the cantilever type. Fixed bearings and floating bearings are provided at the fuselage. Torsion bar springs are mounted to said fixed bearings and said floating bearings, said respective inner end of at least one pivotable cantilever cross beam being attached to said torsion bar spring at the floating bearing in such a manner that moments are transferred from the respective inner end of each pivotable cantilever cross beam via said torsion bar spring to the fuselage at said fixed bearing.

Abstract: Maintenance steps on helicopters (10) comprising a casing (1), integrated into a lateral shell of a fuselage of a helicopter (11) for access from outside and a step (2) being pivotably mounted in the casing (1). The invention relates as well to methods for mounting and dismounting of such maintenance steps.
