Bristol B.R.7

The Bristol B.R.7 was a single engine, two seat biplane built by Bristol in 1913 to a Spanish government order. It was the Renault engined version of the first biplane designed by Henri Coanda, the Romanian designer who had become head designer at the company in January 1912, and the Spanish asked for the 70 hp Renault because they already used it in their Maurice Farmans. A German version was built separately by Deutsche Bristol-Werke with a Daimler engine. The B.R.7 had two bay wings and an unusual four wheel undercarriage, but its wings produced too little lift, and when changes did not bring it up to the specification the Spanish contract was cancelled.
