Extra low profile xlp latching system Hartwell provided a lightweight, low-profile solution with alignment and shear pins incorporated into the housing to carry shear loads and align the two halves of the engine nacelle. The result was Hartwell’s patented Extra-Low Profile XLP™ system. |
 |
Dual pin & hook, full remote latching system Through the process of Solutioneering and working closely with the customer, Hartwell’s engineering team designed a fully remote three-point latch system that operates from a single handle. The system’s design also includes additional safety features that insure proper operation with the added convenience of being functioned by one mechanic instead of two. |

Crew escape hatch & handle The customer was developing a state-of-the-art crew escape door for the Boeing 787. The escape hatch, an inward opening plug-type pressure-only door constructed from monolithic high speed machined aluminum with discrete stops, is intended as an emergency exit for the flight crew and is accessed from both inside and outside the airplane. |
 |
Nacelle hold-open & rate control rods The nacelle was being designed for GE C34-10A engines destined for use aboard the ARJ-21. The customer required a nacelle hold-open/close system that met stringent weight, strength, rate-control and durability standards. |
