Design a telescopic hold‑open rod (HOR) with an integrated lock mechanism capable of supporting weight of cowl doors in the open position. Ended
About the job
Cowl‑door operation : Cowl door is raised using a separate actuation system, with one end of the HOR attached directly to the cowl.
Automatic locking : As the HOR extends, its internal locking mechanism shall automatically engage and secure the rod in the extended position.
Load support : Once locked, the HOR must support the full weight of the cowl door under continuous compressive load without deformation or failure.
Lock integrity under load : The lock mechanism must remain secure under compressive load. Unlocking shall not be possible while the HOR bears the cowl’s weight.
Controlled unlocking: Unlocking is permitted only through a deliberate user action: a combined rotation and axial translation along the HOR’s axis.
Visual Locking Indication: The HOR must feature a visual indicator that clearly distinguishes between locked and unlocked states using contrasting colors. For example:
Green to indicate the locked (safe) state.
Red to indicate the unlocked (unsafe) state.
Architectural Requirement: Proposed HOR needs to fit in a cylindrical envelope of Ø 60 mm, 1160 mm long and weigh less than 2.5 kg. See figure for space envelope
Mechanical Fatigue life: HOR needs to survive without deformation or failure a fatigue life of 4000 cycles. One duty cycle defined as following sequence. open – locked - loaded – unloaded - close
