General Characteristics

The Stearman-Hammond Y-1S was a unique, two-seat experimental aircraft designed in the mid-1930s with safety and ease of control as its primary goals. Its unusual pusher propeller configuration and tricycle landing gear were radical for the time.

Design and Powerplant

  • Engine: One Menasco B6S six-cylinder air-cooled inverted in-line engine.
  • Power Output: 150 hp (112 kW).
  • Propeller: Two-bladed propeller mounted behind the wing trailing edge in a pusher configuration.
  • Landing Gear: Featured a tricycle landing gear (nose wheel and two main wheels), a highly advanced and rare feature in the 1930s, designed to prevent ground looping.
  • Flight Controls: Simplified three-control system. Notably, yaw and roll were controlled by combined rudders/ailerons (“rudderons”), intended to be easier for non-professional pilots.
  • Configuration: High-wing, twin-boom monoplane.

Performance and History

  • Maximum Speed: 204 km/h (127 mph).
  • Cruise Speed: 185 km/h (115 mph).
  • Operational Range: Approximately 725 km (450 miles).
  • Historical Note: The Y-1S won the U.S. Bureau of Air Commerce’s competition for a safe, low-cost private aircraft, but poor sales due to its high price and unusual configuration led to the company’s collapse.
  • Legacy: Although a commercial failure, its innovative design elements, particularly the pusher engine and tricycle gear, influenced later aircraft safety and general aviation design.
