The Cessna Model A was a 1920s American high-wing four-seat tourer built by the Cessna Aircraft Company, the first in long line of high-wing single-engined monoplanes.

Design and development

The first Cessna design built in any numbers was the Cessna Model A, a four-seater with a mixed wood and steel-tube construction with fabric covering. The aircraft was built in a number of variants fitted with different engines.

Variants
Model AA
Fitted with a 120hp (89kW) Anzani 10 engine, 14 built.
Model AC
Fitted with a 130hp (97kW) Comet engine, one built.
Model AF
Fitted with a 150hp (112kW) Floco/Axelson engine, three built.
Model AS
Fitted with a 125hp (93kW) Siemens-Halske engine, four built.
Model AW
Fitted with a 125hp (97kW) Warner Scarab engine, 48 built.
Model BW
A three-seat version with a 220hp (164kW) Wright J-5 engine, 13 built.]]> Tue, 07 Sep 2010 21:59:51 GMT http://www.picturesphoto.info/r-a-37b-dragonfly-20.htm Mon, 09 Jun 2008 00:55:22 GMT
The A-37B was also exported to Latin American air arms, mostly during the 1970s. It was well suited to their needs because of its simplicity, low cost, and effectiveness for insurgent warfare. Most of the A-37Bs exported south had the refueling probe shortened to act as a single-point ground refueling probe, or deleted completely.

Latin American countries that received the A-37B included Peru (36 aircraft), Chile (34), Columbia (14 originally, plus 12 reportedly supplied later), Ecuador (12), Uruguay (8), Honduras (15), Guatemala (13), and El Salvador (18). Super Tweets remain in service in some of these countries in slowly declining numbers.]]> Cessna A37B Dragonfly http://www.picturesphoto.info/r-a-37b-dragonfly-20.htm http://www.picturesphoto.info/r-cessna-a-37b-dragonfly-for-sales-19.htm Mon, 09 Jun 2008 00:54:19 GMT
Modifications were made to control surfaces to improve handling. To improve aircraft and crew survivability, the A-37B was fitted with redundant elevator control runs that were placed as far apart as possible. The ejection seats were armored, the cockpit was lined with nylon flak curtains, and foam-filled self-sealing fuel tanks were installed.

The A-37B added a refueling probe to the nose, leading to pipes wrapped around the lower lip of the canopy, for probe-and-drogue midair refueling. This was an unusual fit for USAF aircraft, which traditionally are configured for boom refueling. Other improvements included updated avionics, a redesigned instrument panel to make the aircraft easier to fly from either seat, an automatic engine inlet de-icing system, and revised landing gear. Like its predecessors, the A-37B was not pressurized.

20 millimeter and 30 millimeter cannon pods were developed for the A-37B to give it more punch, but apparently such pods were rarely or never used in operation.

A total of 577 A-37Bs were built, with 254 delivered to the South Vietnamese Air Force. They reportedly performed well in actions against Communist forces. When South Vietnam fell in early 1975, a South Vietnamese Air Force officer, Captain Nguyen Thanh Trung, defected to the Communists and led strikes against South Vietnamese government positions in his A-37B.

There were about 187 A-37Bs in South Vietnamese hands when the country fell. 92 were recovered by the Americans, while the other 95 were later used by the Communist Vietnamese in missions over Cambodia. These "renegade" aircraft were phased out of service in the late 1970s or early 1980s, no doubt due to lack of spares.]]> Cessna A37B Dragonfly http://www.picturesphoto.info/r-cessna-a-37b-dragonfly-for-sales-19.htm http://www.picturesphoto.info/r-air-to-air-cessna-a-37b-dragonfly-sales-18.htm Mon, 09 Jun 2008 00:53:04 GMT
The Combat Dragon program was very successful, but unsurprisingly the combat evaluation revealed some of the deficiencies of the A-37A. The worst problem was that the aircraft lacked range and endurance. Other concerns were heavy control response during attack runs and the vulnerability of the aircraft's non-redundant flight control system.

The USAF signed a contract with Cessna in early 1967 for an improved Super Tweet, designated the "A-37B". The initial order was for 57 aircraft, but this was quickly increased to 127. The A-37Bs were primarily intended to be supplied to the South Vietnamese Air Force as replacements for their Skyraiders. The A-37B prototype was rolled out in September 1967, with deliveries to the South Vietnamese beginning in 1968.

The A-37Bs were all new-build aircraft. They were stronger than the A-37A, stressed to 6 gees instead of 5, and had a longer fatigue life of 4,000 hours. Field experience would show that 7,000 hours was more in line with reality.

The A-37B weighed almost twice as much as the T-37C. A remarkable fraction of the loaded weight, 2.67 tonnes (5,880 pounds), could be external stores. In practice, the A-37B usually operated with at least two and sometimes four underwing fuel tanks to improve combat endurance.]]> Cessna A37B Dragonfly http://www.picturesphoto.info/r-air-to-air-cessna-a-37b-dragonfly-sales-18.htm http://www.picturesphoto.info/r-cessna-a-37b-dragonfly-sales-17.htm Mon, 09 Jun 2008 00:51:45 GMT
