The present technology relates to an actuating system (200), including a latching and locking system, for an actuatable door (201). The actuating system (200) comprises a rotatable drive shaft (210), a rotatable latch shaft (225), a latching device (220), and a locking device (260). The latching device (220) includes at least two latches (230), a latch securing unit (300) for maintaining the at least two latches (230) in the latched position (335), and at least two lock lever counterparts (264, 266). The locking device (260) includes a lock lever (262) for engaging with the at least two lock lever counterparts (264, 266) to prevent the latch securing unit (300) from disengaging from the securing position (365), thereby locking the at least two latches (230) in the latched position (335) when the lock lever (262) is in a locked position (460).

The invention relates to a battery and an electrical battery monitoring device comprising a first group of sensing switches (13) connected in series on a first monitoring circuit (11), said sensing switches, a second group of electrical sensing switches (14) connected in series on a second monitoring circuit (12), an input unit (16) to provide an input to the first and second monitoring circuits, a monitoring unit (17) to receive an output from the first and second monitoring circuits, wherein the monitoring unit receives at least two outputs from two measuring points of the first monitoring circuit, the two measuring points being separated by at least one sensing switch. The location of a defective battery cell may be early detected and precisely located by the monitoring of the battery cells in rows and columns.

A non-retractable wheel-type landing gear (8) for a rotorcraft, comprising: at least one wheel (8a); a shock absorber (8b) with a circumferential direction (8o), which is connected to the at least one wheel (8a) and comprises a shock absorber tube (8c) and a shock absorber rod (8d) telescopically mounted to the shock absorber tube (8c); a mounting arm (8e) extending laterally from the shock absorber tube (8c), the mounting arm (8e) being integrally formed with the shock absorber tube (8c) and adapted for attachment to a first fitting (14) of a rotorcraft; and a link fixation (8i) extending laterally from the shock absorber tube (8c), the link fixation (8i) being arranged in the circumferential direction (8o) of the shock absorber (8b) at an angle in a range from 45° to 120° with respect to the mounting arm (8e) and adapted for connection to a second fitting (15) of the rotorcraft.

The present embodiments relate to an opening system 300 for a swiveling aircraft door 200, to a swiveling aircraft door 200 with such an opening system 300, and to an aircraft 100 comprising such a swiveling aircraft door 200. The opening system 300 includes a hinge bracket 410, a swivel mechanism 420, a hold-open latch 430, and an actuator 460. The hold-open latch 430 is in an unclamped state 432 when the swiveling aircraft door 200 is in the closed position 305 and latches in an over-centered state 434 when the swiveling aircraft door 200 is in the fully open position 308 to prevent the swiveling aircraft door 200 from returning to the closed position 305. The actuator 460 acts on the hold-open latch 430 that in turn acts on the swivel mechanism 420, thereby performing the opening and closing swivel movements of the swiveling aircraft door 200.

A non-pressurized aircraft (100) comprising a hinged door with a door leaf (160) is disclosed. The non-pressurized aircraft (100) includes a canopy frame (370) with a canopy frame cross-section profile (375). The canopy frame cross section profile (375) has first and second canopy frame faces (371), (372) that are arranged at a predetermined angle (397) relative to each other, and a third canopy frame face (373) that is arranged between the first and second canopy frame faces (371), (372). The non-pressurized aircraft (100) further includes a hinge (220) that is entirely arranged within the outline (310) of the non-pressurized aircraft (100) and pivotally mounts the door leaf (160) to the third canopy frame face (373).
