Swedish police with a Bell 429 A Eurocopter AS365 N3 Dauphin 2 of the Victoria Police Air Wing.. Police aviation is the use of aircraft in police operations. Police services commonly use aircraft for traffic control, ground support, search and rescue, high-speed car pursuits, observation, air patrol and control of large-scale public events and/or public order incidents.
The Police and Border Guard Aviation Group operates fixed and rotary-wing aircraft for the Police and Border Guard Board. In total, they operate three helicopters and two airplanes. [18] One of the airplanes is equipped for maritime patrol and pollution detection duties. [19]
The rotor system, or more simply rotor, is the rotating part of a helicopter that generates lift. A rotor system may be mounted horizontally, as main rotors are, providing lift vertically, or it may be mounted vertically, such as a tail rotor, to provide horizontal thrust to counteract torque from the main rotors.
The final design of Proteus was revealed in January 2025. Its airframe is derived from the Kopter AW09 single-engine light helicopter and shares its shrouded anti-torque system and five-bladed rotor. It is designed to carry modular payloads which can be interchanged to meet different mission requirements, such as at-sea replenishment and anti ...
Worldwide, over 1,000 autogyros are used by authorities for military and law enforcement. The first U.S. police authorities to evaluate an autogyro were the Tomball, Texas, police, on a $40,000 [28] grant from the U.S. Department of Justice together with city funds, [29] [30] costing much less than a helicopter to buy ($75,000) and operate ($50 ...
NOTAR, an acronym for no tail rotor, is a helicopter anti-torque system that eliminates the use of the tail rotor on a helicopter. Although the concept took some time to refine, the NOTAR system is simple in theory and provides antitorque the same way a wing develops lift by using the Coandă effect. [27]
A police aircraft is a rotary-wing aircraft, fixed-wing aircraft, nonrigid-wing aircraft or lighter-than-air aircraft used in police operations. They are commonly used for traffic control, ground support, search and rescue , high-speed car pursuits, observation, air patrol, riot control, and police tactical unit transportation.
Some rotary wing aircraft are designed to stop the rotor for forward flight so that it then acts as a fixed wing. For vertical flight and hovering it spins to act as a rotary wing or rotor, and for forward flight at speed it stops to act as a fixed wing providing some or all of the lift required. Additional fixed wings may also be provided to ...
