1912 British Mersey Monoplane
It was a side by side 2 seater. The 1/2 reduction drive shaft passed between the seats. The span was 35 feet, chord 7 feet, area 220 sq ft, length 24 feet, weight 750 lbs empty and 1,150 fueled and occupied and top speed was 55 mph. The power was from a 7 cylinder radial of somewhere between 45 and 60 HP. with the prop running at 1/2 engine rpm. The fuselage was 7 foot long (same as the cord). It held enough fuel to fly 6 hours. The number it had on it's tail during the trials was 19.The Mersey was a British aircraft built in 1911. The plane was built by R.C. Fenwick and S.T. Swaby, who met at Planes Ltd. Fenwick designed and piloted the plane in 1911. "Janes" lists the plane as a 1912 model with a 60 HP Isaacson Radial motor but Goodall and Tagg say it had a 45 HP Isaacson 7 cylinder radial. After test flights Fenwick enlarged the vertical and horizontal tail surfaces to present configuration.The plane competed in the British Military Trials of August 1912 and was said to have done quite well ( top 3) in spite of the fact that it crashed in the wind near Stonehenge and killed Fenwick.
