INNOVATION May-June 2017

Tank reduces time and costs for remote fuel deliveries Bering Air sought a better way of using its Bell 412 helicopter to deliver fuel to remote cell towers, which are often located on the top of mountains. The to haul fuel in, then, after unloading the fuel, haul paying cargo back out, instead of the common practice of flying empty fuel drums out. Because the tank is not a slung load, the helicopter can fly at full speed, which

The Vancouver Airport Authority (YVR) is implementing Runway End Safety Areas (RESAs) for its runways in order to meet new Transport Canada safety requirements. A RESA provides a surface at the end of a runway strip that would help reduce the severity of damage to an aircraft in the event of the aircraft undershooting, overrunning, or veering off the runway during landing or take off, as well as facilitating the movement of rescue and fire fighting vehicles. Hatch is providing detailed design and construction inspection services for the first phase of the project, which involves Bell 412 helicopter offers an ideal airframe for hauling fuel inside the aircraft, except for the location of its challenging centre rotor mast. Tasked with finding a solution, SEI Industries Ltd. developed a new fuel- hauling container that combines SEI’s award-winning fabric BATT inner tank with a strong aluminum outer tank. With built-in wave baffling, the BATT hybrid tank allows Bell 412 helicopters DaamBuilt is a North Vancouver, BC- based custom bicycle frame–building company that uses engineering techniques to achieve fabrication efficiencies and to develop innovative designs that enhance the rider’s experience.  DaamBuilt designed this full- suspension frame for a client who wanted custom geometry and an efficient suspension platform. The suspension linkage was designed by selecting a leverage ratio, anti-rise and anti-squat values to match the

also reduces costs and time. Now ready for the marketplace, the BATT 412 hybrid tank meets all requirements for flight safety and requires no heavy equipment. It can be assembled and disassembled inside the aircraft by two people. APEGBC member: Victor Yaremenko, P.Eng.

Runway safety improved at Vancouver International Airport

implementing RESAs on Runway 08R-26L—the airport’s longest runway on the south—and Runway 13-31—the crosswind runway. The project includes a paved extension of the east end of the south runway, with site works including removals, excavation, sand preload/surcharge, construction of new flexible and rigid pavement structures, new storm drainage, relocation of the 08R localizer, relocation of underground utilities and navigation aids, and installation of airfield lighting and infrastructures.

Engineering improves mountain bike design

climbing and pedalling traits best suited to tackle the BC North Shore’s toughest trails. To build this comfortable yet aggressive frame, the company’s engineer used aerospace-grade butted steel tubes for the main triangles and machined billet aluminum for the linkage plates. These materials balance weight and strength while maintaining the classic lively feel of a steel bicycle frame. APEGBC member: Peter Daam, P.Eng.
