Sikorsky Aircraft and Boeing are jointly producing a medium-lift-sized demonstrator they named SB>1 Defiant [3] [4] (also widely known as "SB-1") [5] [6] for phase one of the program. Originally planned to fly in late 2017, its first flight was delayed in April 2017 to early 2018. [7]
The Defiant is built using fiberglass layup over Styrofoam core shapes in the same manner as the Rutan VariEze. The main gear is fixed, and there are no flaps. The Propellers are fixed-pitch non-feathering, [3] which is unusual in a twin-engine design. Cockpit entry is through a side hinged canopy. [1] The winglets provide yaw stability. [3]
The timer may switch equipment on, off, or both, at a preset time or times, after a preset interval, or cyclically. A countdown time switch switches power, usually off, after a preset time. A cyclical timer switches equipment both on and off at preset times over a period, then repeats the cycle; the period is usually 24 hours or 7 days.
Mechanical timers use clockwork to measure time. [1] Manual timers are typically set by turning a dial to the time interval desired, turning the dial stores energy in a mainspring to run the mechanism. They function similarly to a mechanical alarm clock, the energy in the mainspring causes a balance wheel to rotate back and forth. Each swing of ...
