The Blériot 137 , also known as the Blériot Bl-137, was a multi-purpose military aircraft produced by the French manufacturer Blériot Aéronautique .

The aircraft was a further development of the Blériot 127 in all-metal construction. Contrary to the unusually arranged rear gunner positions of the 127, these were located in an incision in the wing trailing edge of the 137.

The aircraft was never built in series, only 2 slightly different prototypes were made.

construction

The Blériot 137 was a shoulder- wing aircraft constructed from metal . The open cockpit with double controls for pilots and co-pilots was located approximately at the level of the leading edge of the wing.

A weapon stand was located in the nose of the fuselage, and there was also a weapon stand in the stern of the motor gondolas, these positions could be reached by the gunner in flight over the center wing.

The landing gear was not retractable and consisted of the main landing gear and a tail spur.
