Dragonfly Airplane - And manufactured by Viking Aircraft LLC of Elkhorn, Wisconsin. The plane is available as a kit or as a hobbyist build plan.
The Dragonfly is a two-seat split-wing aircraft with one wing pointing down and the other behind the fuselage in the shoulder position. . Fixed landing gear and single gen in tractor configuration. The cockpit is 43 in (109 cm) wide

The aircraft was built from composites, based on construction techniques pioneered by Burt Rutan at the Rutan Aircraft Factory (RAF). The airframe design is visually similar to the RAF's Quickie 2, which was developed in depth, but the Dragonfly has larger airfoils and a smaller fuselage, resulting in a slower but more stable lift aircraft. Its rear wing uses a 20 ft (6.1 ft) GU25-5 (11) 8 Mod airfoil, while the rear wing (22 ft long) uses an Eppler 1212 airfoil.

). Standard engines used include a 60 hp (45 kW) Volkswagen air-cooled engine and an 85 hp (63 kW) Jabiru 2200 four-stroke powerplant. The construction time of the supplied kit is estimated as 700 hours, while the plans are about 1200 hours.
The original version had the main landing gear mounted on the lower wing spars in the aircraft. The Cessna A-37 Dragonfly, or Super Tweet, is an American light attack aircraft developed from the T-37 Tweet basic trainer in the 1960s and 1970s by Cessna of Wichita, Kansas. The A-37 was introduced during the Vietnam War and later continued in peacetime service.
Increased US military involvement in Vietnam in the early 1960s led to increased interest in counterinsurgency (COIN) aircraft. In late 1962, the US
The Air Force saw the T-37 as promising, but wanted an advanced version of the aircraft capable of carrying a much larger payload, and with much longer endurance and better short-field performance. This means a heavier aircraft with more powerful engines. In 1963, the Air Force awarded SSNA a contract for two prototype Yat-37D aircraft: the H-37 with modifications that included:

The change served to increase the weight of the aircraft and the aircraft now has to carry a significant amount of cargo. Therefore, Cessna doubled the engine power by replacing the two Continental J-69 engines with Geral Electric J85-J2/5 turbojet engines with 2, 400 lbf (11 kN) each.
The first Yat-37D flew in October 1964, a year after the second prototype. The second prototype had four storage racks under each wing, not three, and the first prototype was also updated with this configuration.
Test results were good, but USAF interest in counterinsurgency (COIN) aircraft for MOMT has faded. The program has been on hiatus for some time, with the second prototype "put out to pasture" at the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Ohio.
The war in Southeast Asia is increasing. The loss of Douglas A-1 Skyraider close support aircraft in the USAF, US Navy and Republic of Vietnam Air Force Service was greater than expected and USAF interest in Coin aircraft was revived. The YAT-37D seemed like a promising candidate for the job, but the Air Force felt the only way to be sure was to evaluate the aircraft in combat.

As a result, the USAF awarded a contract to Cessna for a pre-production batch of 39 YAT-37Ds, with a few minor modifications to the prototypes to be rebuilt from existing T-37Bs. The aircraft were initially designated the AT-37D, but the designation was soon changed to the A-37A. The second prototype YAT-37D was removed from the Air Force Museum and upgraded to A-37A standards as part of the test program.
The A-37A had a total takeoff weight of 12,000 lb (5,400 kg), which included 2,700 lb (1,200 kg) of ammunition. The A-37A retained the dual control of its T-37B ancestor, allowing it to be used as an operational trainer.
During "Forward Air Control (FAC)" combat operations, the second seat was occupied by the observer. Only one crew usually flew in the aircraft for close support missions, allowing for a small increase in ammunition.
In August 1967, 25 A-37 AS were deployed to Vietnam under the "Combat Dragon" evaluation program, and from Bi Hoa Air Base on USAF "Air Commando" missions, including air support of close, helicopter escort, FAC and night interception flown. Warheads included high-explosive bombs, cluster bomb launchers, unguided rocket packs, napalm tanks and the SUU-11/A minigun. For most missions, the aircraft also carried two additional external fuel tanks on internal stores racks.

During this period, the A-37AS flew thousands of sorties. None of the Amy Fires were lost, although two died in landing accidents. The A-37A was officially named the "Dragonfly", but most pilots called it the "Super Tweet". The Combat Dragon program was a success, but not surprisingly, combat evaluation revealed some of the A-37A's shortcomings. The most obvious problem was that the aircraft was lacking in size and durability. Other concerns are the rough control response during an attack run (the flight controls are not powered up) and the vulnerability of the aircraft's non-volatile flight control system.
The USAF signed a contract with Cessna in early 1967 for an improved Super Tweet, called the "A-37B". The initial order was for 57 aircraft, but this quickly increased to 127. The A-37Bs were primarily intended to be supplied to the Republic of Vietnam Air Force (ROVNAF) as replacements for their A-1 fighters. The A-37B prototype was rolled out in September 1967, with deliveries to South Vietnam beginning in 1968.
The A-37Bs are all new aircraft. These were more powerful than the A-37A's, able to pull 6 g instead of 5 g, and were designed to have a longer fatigue life of 4,000 hours. Field experience will show that 7,000 hours between renewals can be tolerated.
The A-37B is almost twice as heavy as the T-37C. A significant portion of the payload, 5,800 lb (2,600 kg), can be stored externally. In practice, the A-37B usually operates with at least two and sometimes four underbody fuel tanks to improve combat longevity.

To accommodate the extra weight, the A-37B is equipped with Geral Electric J85-GE-17A engines, each providing 2,850 lbf (12.7 kN) of thrust. The jeans are angled slightly outwards and downwards to improve the one-woman fit. Air Commando pilots in Vietnam who operated the A-37A found the single-engine cruise an effective tool for improving their flight duration.
Changes are made to control surfaces to improve handling. To improve aircraft and crew survivability, the A-37B was equipped with additional elevator control tracks located as far apart as possible. The ejection seats were armored, the cockpit was covered with nylon mesh curtains, and the fuel tanks were filled with foam, which were self-sealing.
The A-37 was successful in close air support. It can engage targets at speeds of up to 100 miles per hour faster than lean-wing fighters. The slow speed improved bombing accuracy, allowing pilots to achieve an average accuracy of 45 feet (14 m).
The A-37B added a fuel probe in the nose, which led to pipes wrapped around the lower lip of the canister, for probe-and-drogue aerial fueling. This was an unusual fit for USAF aircraft, traditionally configured for boom fuel. Other improvements include upgraded avionics, a redesigned instrument panel to make the aircraft easier to fly from any seat, an automatic Jane de-icing system and revised landing gear. Like its predecessors, the A-37B is not pressurized.

The A-37 requires relatively little maintenance compared to contemporary fighters - just two hours of maintenance for every hour of flight time. This was partly due to the multiple access panels in strategic locations.
The 20 mm (0.787 in) GPU-2/A and AMD 30 mm (1.18 in) cannonballs were tested with positive results on the A-37B,
A total of 577 A-37Bs were built, with 254 delivered to the RVNAF. In World War II, the A-37 flew over 160,000 combat missions with only 22 USAF losses.
When North Vietnamese forces captured Da Nang Air Base on D-March 1975, they captured a large amount of stores and equipment, including 33 intact A-37s.

On April 28, 1975, several captured A-37s were used by the North Vietnamese to attack Tan Son Nhut Air Base, still held by the South Vietnamese.
About 187 A-37Bs were in rescue service during the fall of Saigon in April 1975. 92 were acquired by the US Air Force. United States, but another 95 were later used by the People's Air Force of Vietnam in missions over Cambodia and during the China war in 1979. spare parts. Some aircraft were sent to Vietnam's communist allies such as Czechoslovakia, Poland, the Soviet Union and East Germany.
Others were sold to private foreign owners. Six examples of the A-37B have been owned by American war enthusiasts, while four A-37Bs are now privately owned in Australia and New Zealand.
After the war, the USAF transferred its A-37Bs from the USAF Tactical Airlift Command (TAC) to the units that acquired the TAC.
