Sikorsky Cypher UAV Papercraft

Aircraft

Written by Julius Perdana Sunday, 10 May 2009 20:16

The Sikorsky Cypher and Cypher II are types of unmanned aerial vehicles developed by Sikorsky Aircraft Corporation. They are vertical takeoff and landing aircraft which use two opposing rotors enclosed in a circular shroud for propulsion.

In the late 1980s, Sikorsky Aircraft flew a small UAV named "Cypher", with coaxial rotors inside a torus-shaped airframe. The torus shroud improved handling safety and also helped increase lift. The first proof-of-concept Cypher was 1.75 meters (5.75 feet) in diameter and 55 centimeters (1.8 feet) tall, weighed 20 kilograms (43 pounds), and was first flown in the summer of 1988. This design was powered by a four-stroke, 2.85 kW (3.8 hp) engine and was mounted on a truck for forward-flight tests.[Wikipedia]

The MQ-1 Predator is an unmanned aerial vehicle (UAV) which the United States Air Force describes as a MALE (medium-altitude, long-endurance) UAV system. It can serve in a reconnaissance role and fire two AGM-114 Hellfire missiles. The aircraft, in use since 1995, has seen combat over Afghanistan, Pakistan, Bosnia, Serbia, Iraq, and Yemen. It is a remote-controlled aircraft.

The MQ-1 Predator is a system, not just an aircraft. The fully operational system consists of four air vehicles (with sensors), a ground control station (GCS), a Predator primary satellite link communication suite, and 55 people. In the over-all U.S. Air Force integrated UAV system the Predator is considered a "Tier II" vehicle [Wikipedia]
