From Wikipedia, the free encyclopedia

Embraer/Neiva EMB-202 Ipanema

The Embraer EMB 202 Ipanema is an agricultural aircraft used for aerial application, particullary crop dusting. It's produced by Indústria Aeronáutica Neiva, a subsidiary of Embraer located in the city of Botucatu. The latest version of this aircraft is the first alcohol-powered fixed-wing aircraft, which gives it many economical and ecological advantages over the gasoline version. The aircraft is widely employed on Brazil, having market share of about 80%, and completed 1,000 deliveries on March 15, 2005. Besides aircraft, alcohol-conversion kits for gasoline-powered Ipanemas are also sold. It's common to think that the Ipanema name comes from the Rio de Janeiro beach, but it actually comes from a farm of the same name owned by the Brazilian Ministry of Agriculture.

[edit] Development

On the 1960s, the development of a Brazilian agriculture aircraft was motivated by the expansion of agricultural products' market, specially soybean and sugar cane. During this time, the Ipanema aircraft was developed by engineers of the Aeronautics Technological Institute (ITA) on the Ipanema Farm, located on Sorocaba.

The first version of the aircraft, the EMB-200, made its first flight on 1970 and was certified on December 1971. The aircraft was equipped with a 260 HP propeller. Series production started on 1972 by Embraer. On September 1974, the EMB-201 was released, including many improvements such as a 300 HP propeller, new blades, new wings and increased capacity.

On 1982, the production of Ipanema was transferred to Indústria Aeronáutica Neiva, recently acquired by Embraer. On 1992, a new model, called EMB-202 or Ipanemão, was released. The new aircraft had improvements on aerodynamics, a 40% greater capacity, and an optional, modern equipment for electrostatic aerial application.

On the following years, Neiva made significant improvements on the aircraft, such as adding winglets on the wing tips, adding an air conditioning system on the cabin, lowering the position of the wings, increasing the resistance and reducing the weight of the exhaust system and other changes.

Since ethanol is largely available on Brazil, being three to four times less expensive than aviation gasoline, many Brazilian farmers have attempted to fuel gasoline-powered Ipanemas with alcohol, with variable degrees of success. The result of this was a development of an alcohol-powered Ipanema, which was certified by the Brazilian General Command for Aerospace Technology (CTA) on October 19, 2004. The new propeller of the Ipanema had also 20% lower maintenance and operational costs.
