A trimotor is a propeller-driven aircraft powered by three internal combustion engines, characteristically one on the nose and one on each wing. A compromise between complexity and safety, such a configuration was typically a result of the limited power of the engines available to the designer. Many trimotors were designed and built in the 1920s and 1930s as the most effective means of maximizing payload.
