Velocity SE. The Rocket Racer on landing roll-out at Mojave. The Velocity Model 173 SE (Standard Elite) is an entry-level canard pusher aircraft from Velocity Aircraft. [1][2][3] The four seat, rear engine aircraft may be powered by a 160 hp (120 kW) Lycoming IO-320 or a 200 hp (150 kW) Lycoming IO-360 engine. [1]
The Velocity XL is 12 in (310 mm) longer and has a 20 in (510 mm) greater span than the SE. [3] The standard XL has a cruising range of 875 nautical miles (1,620 km; 1,007 mi) and a 75% power cruising speed of 185 knots (213 mph; 343 km/h) air speed. [2][4][5] The XL is available in both fixed gear (FG) and retractable gear (RG) form and can ...
Ballistic missile. 1. The missile launches out of its silo by firing its 1st-stage boost motor (A). 2. About 60 seconds after launch, the 1st-stage drops off and the 2nd-stage motor (B) ignites. The missile shroud (E) is ejected. 3. About 120 seconds after launch, the 3rd-stage motor (C) ignites and separates from the 2nd stage.
Doubly fed electric machines, also slip-ring generators, are electric motors or electric generators, where both the field magnet windings and armature windings are separately connected to equipment outside the machine. By feeding adjustable frequency AC power to the field windings, the magnetic field can be made to rotate, allowing variation in ...
The EMD DE30AC and DM30AC are a class of 46 locomotives built between 1997–1999 by Electro-Motive Division in the Super Steel Plant in Schenectady, New York, for the Long Island Rail Road of the Metropolitan Transportation Authority (MTA) in New York. Originally divided equally between the two types, the fleet currently consists of 24 DE30AC ...
The aircraft features a cantilever low wing, a four-seat enclosed cabin that is 46 in (117 cm) wide, fixed tricycle landing gear and a single engine in tractor configuration. [1] The aircraft is made from composites. Its 35.5 ft (10.8 m) span wing employs a McWilliams RXM5-217 airfoil at the wing root, transitioning to a NACA 64-212 at the wingtip.
The rotors are designed to operate at a fixed RPM [3] [4] [5] (within a narrow range of a few percent), [6] [7] but a few experimental aircraft used variable speed rotors. [8] Unlike the small diameter fans used in turbofan jet engines, the main rotor on a helicopter has a large diameter that lets it accelerate a large volume of air. This ...
AC50. The AC50 (defined in the America's Cup rules as AC Class yacht, or ACC) was a wingsail catamaran development rule that governed the construction of the yachts used in the 2017 Louis Vuitton Cup and the 2017 America's Cup. Like the larger AC72s used in the 2013 America's Cup, AC50s used L-shaped daggerboard stabilizers as well as T-shaped ...
