With the gradual maturity of uav technology, in the 1930s, the British government decided to develop an unmanned target aircraft to test the effectiveness of artillery on battleships against aircraft. In January 1933, the "Ferrer Kunz" uav converted from "Ferrer" seaplane was successfully tested. Shortly thereafter, the UK developed an all-timber, two-winged drone called the DE Havilland moth. Between 1934 and 1943, 420 uAVs were produced and renamed "Queen Bee".
The British were ahead of the game, and the Americans were not far behind. Sperry and Delco developed the first drone in the United States as early as 1915. Weighing just 272kg, the drone is powered by a 30-kilowatt piston engine and is mounted on a four-wheel scooter with grass rails. After the plane is started, drive the tackle on the slide. After reaching a certain speed, the plane would get off the skid and fly into the sky. Then a simple gyroscope device would control the flight direction and a capsule barometer would automatically control the flight altitude. In 1915, the drone, which was named aerial Torpedo, not only made successful test flights, but also successfully tested its target with 136 kilograms of explosives.
Shortly thereafter, Charles F. Catlin of the United States Army developed a drone called the Catlin Fly. The aircraft, similar to an ordinary biplane, weighs 238.5 kilograms and can carry 82 kilograms of bombs. It can fly at a speed of 88 kilometers per hour. The U.S. Army began test flights of the Kettering Bug in September 1918 and finally put it into the sky on October 22.
In the 1930s an American aviation expert named Reginald Derry developed the radio-controlled aircraft for target shooting for the United States Army. In 1939, the United States also developed a upper single-wing uav, named RP-4.
In 1941, the attack on Pearl Harbor occurred. Due to war needs, the U.S. Army and Navy began to order a large number of target aircraft, including 984 OQ-2A target aircraft, 9,403 OQ-3 target aircraft, and 3,548 OQ-13 target aircraft. The latter two are equipped with powerful engines and can fly at speeds of up to 225 kilometers per hour and at altitudes of up to 3,000 meters.
In World War II, the U.S. Army Air Corps used unmanned target aircraft extensively, and in the Pacific theater used piston-engined drones with heavy bombs to bomb Japanese targets. During the war, the MILITARY also planned to convert its defunct B-17 and B-24 bombers into remote-controlled bombers to carry bombs. The pilot drives the bomber to the beach, parachutes out, and the bomber flies under radio control until it strikes its target. But the cost and the complexity of the technology meant the army abandoned the project. During this period, the US Navy also developed three jet uAVs, named "Glauber", "Fugan" and "Gaegler", but for various reasons, they were not formally equipped for military service.
After World War II, with the rapid development of aviation technology, the uav family gradually entered its heyday. Up to now, there are nearly 100 kinds of uav developed and produced in the world, and some new models are under development. With the development of computer technology, automatic pilot technology and remote control and telemetry technology and the application in uav, as well as the in-depth research on uav tactics, uav is increasingly widely used in military, known as the "air versatile", "air favorite".
An unmanned aircraft called the Falcon HTV-2 is capable of flying at 20 times the speed of sound. It is expected to travel from New York to Los Angeles in less than 12 minutes, compared with a normal flight of at least five hours.
The Falcon HTV-2 will be launched from a rocket and then speed down to earth at 13,000 miles per hour. The previous test flight lasted only nine minutes and landed safely in a deliberate crash due to technical difficulties. The test flight was very successful, refreshing a new suborbital space flight and preparing for the generation of a new generation of super weapons. The Falcon HTV-2 will be launched August 11, EDT, from Vandenberg Air Force Base in California, aboard an Air Force Minottir IV rocket, provided weather conditions are favorable. The launch was initially scheduled for August 10.
The project was jointly developed by the Pentagon and the Defense Advanced Research Projects Agency (DARPA) as part of a program to develop a new generation of hypersonic weapons that could hit faster than rockets. The U.S. military hopes the new drone will be able to strike terrorists or government-in-exile anywhere in the world within an hour. The capability is called the Conventional Timed Global Strike System (CPGS).
On the first test flight, in April 2010, DARPA engineers failed to detect exactly what was wrong. Some have speculated that the aircraft may have been overheated while on board. For the second test mission, a series of adjustments have been made, including changing the center of gravity and reducing the Angle of descent.
"We're going to look at addressing some of the challenges, such as sustained hypersonic flight," said Dave Neyland, director of darpa's office of Program Tactics and Strategy. We need to improve our technical knowledge to facilitate the development of hypersonic technology in the future. We gained valuable information from the first flight and made some adjustments based on the findings of the Engineering Review Board, which will help improve the second flight test. Now we are ready to go all out for this test."
On March 17, 2005, Honeywell International announced that it had received a systems engineering contract to analyze the differences between the Defense Advanced Research Projects Agency's (DARPA) Miniature Unmanned Aerial Vehicle (MAV) and the Army's Future Combat System (FCS) Level 1 unmanned aerial vehicle (UAV) systems.
As part of DARPA's Advanced Proof-of-concept Program, Honeywell International developed the MAV, says Steve Cknight, Program manager for Honeywell International's FCS Level 1 UAV Systems. The contract, another milestone for Honeywell, reflects the army's start to develop variants of the MAV technology for the battlefield.
Boeing and Scientific Applications International are FCS 'leading systems integrators. Honeywell said its contract with the lead systems integrator includes a feasibility study for the MAV variant, as well as the drone's portable video and infrared cameras.
The MAV is equipped with forward - and down-view video cameras that transmit information to remote ground station video terminals. Honeywell's variant drones will be equipped with infrared cameras. The drone is designed to provide soldiers with improved situational awareness to protect them from enemy fire. The uav will be used for reconnaissance, security and target search in open, undulating, complex and urban terrain. Using vertical take-off and landing, they can fly under trees, under clouds and in jungles.
FCS will use advanced communications and technology to link warfighters with manned and unmanned ground and air platforms and sensors. FCS allows troops to move quickly and perform a variety of tasks.
