MQ-18 Hummingbird is an unmanned flying machine, which is very similar to a conventional helicopter. But unlike standard helicopters it lacks a system of constant velocity of rotation of the main rotor. Instead, they have developed a unique system optimization rotational speed of the screw, which allows the operator to adjust for different heights, loads and speeds revs, increasing the efficiency of use of fuel and flight time.
Initially, the project indexed A160. Its creator - Frontier Systems Inc. In May 2004 year it bought the company "Boeing". But until then Frontier Systems Inc has designed a UAV mounted piston engine as the US Air Force was interested in it, in addition, the company expects to sell UAVs to the Department of National Security, military organizations and foreign security services.
A little later, in obedience "Boeing", the engineers replaced 4-cylinder engine on 6-cylinder. In addition to the tests worked out the possibility of long-term installation, but still the first option proved himself better.
The project was designed so that the compartments A160 were quite roomy for the premises to various equipment at the same time allowing to conduct exploration, reconnaissance, surveillance, relaying data to detect the target, air strikes and applied to solve other tasks during the same flight. Outside, it was possible to install the module for transport and delivery of a payload weighing up to 454 kg. Military greatly interested new ability UAVs - to linger for a long time in the air at high altitudes. In particular, such a curiosity was due to the military campaign in Afghanistan, where urgently needed intelligence. Also, special attention to future MQ-18 pay special operations forces of the United States.
In May, representatives of the mtrs 2009 US carried out the order for Hummingbird A20T 160 units for reconnaissance and attack purposes. It was decided to finance the program right up to 2017 years.
The first flight of the UAV made in the year 2002, 6 years and over due to a variety of tests and upgrades the machine was able to stay in the air almost 18,7 hours. Thus, the UAV was able to get an unofficial world record for the like classes.
In 2009, former A160T was officially renamed the YMQ-18A. In the same year, "Boeing" signed a contract for the production of UAVs for 20 units MTR USA. In 2010 year deployed three systems with radar Forester.
