CEA CB-2 Minuano
Encyclopedia
The CB-2 Minuano is a high performance sailplane developed by EEUFMG - Escola de Engenharia da Universidade Federal de Minas Gerais - School of Engineering at the Federal University of Minas Gerais in Brazil
between 1969 and 1975 .
Motivated by the knowledge acquired through experience with the CEA CB-1 Gaivota, the design of CEA102-CB.2-Minuano began, becoming the most efficient sailplane designed and built in Brazil (L/Dmax=38), making use of flaps, retract landing gear
, as well as combining aluminium
, wood
, and honeycomb
in its structure. In 1975, the first prototype Minuano made its first flight test
as a cornerstone for the establishment of the aeronautical engineering course at UFMG.

- WingspanWingspanThe wingspan of an airplane or a bird, is the distance from one wingtip to the other wingtip. For example, the Boeing 777 has a wingspan of about ; and a Wandering Albatross caught in 1965 had a wingspan of , the official record for a living bird.The term wingspan, more technically extent, is...

- Aspect ratioAspect ratioThe aspect ratio of a shape is the ratio of its longer dimension to its shorter dimension. It may be applied to two characteristic dimensions of a three-dimensional shape, such as the ratio of the longest and shortest axis, or for symmetrical objects that are described by just two measurements,...
