Construido	Unknow

el Grumman G-164C Ag-Cat es una variante del Grumman G-164 Ag-Cat, un avión agrícola biplano monomotor que fue desarrollado por Grumman en la década de 1950. El Ag-Cat fue el primer avión diseñado específicamente por una importante compañía aeronáutica para la aviación agrícola, y representó una mejora significativa en la seguridad y la fiabilidad con respecto a los plumeros convertidos. El Ag-Cat fue producido inicialmente por Schweizer Aircraft bajo contrato con Grumman, y más tarde por otros fabricantes. El modelo G-164C fue introducido en 1995 por Ag-Cat Corp., y contaba con un motor turbohélice Pratt & Whitney PT6A-34AG de 750 hp, una mayor capacidad de tolva, visibilidad mejorada de la cabina y un nuevo diseño de cola. El G-164C Ag-Cat puede transportar hasta 400 galones de líquido o 3,000 libras de productos químicos secos, y puede operar desde campos cortos y accidentados. El G-164C Ag-Cat se utiliza ampliamente para la fumigación de cultivos, la pulverización, la siembra y las operaciones de extinción de incendios en todo el mundo.

General Characteristics

The Grumman G-164 Ag-Cat was the first aircraft specifically designed by a major company for agricultural aviation (crop dusting/spraying). Its rugged biplane structure, low stall speed, and excellent visibility made it ideal for demanding, low-altitude agricultural maneuvers. The G-164C is a later, enlarged variant known for its increased hopper capacity.

Design and Powerplant

Engine: Pratt & Whitney R-1340 radial piston engine (Wasp).
Power Output: 450 kW (600 hp).
Fuselage Construction: Welded steel tubing truss covered with easily removable aluminum panels (for cleaning corrosive chemicals).
Cockpit: Single, elevated, and typically open (or canopy fitted) cockpit with a reinforced overturn structure for pilot safety. The cockpit is often pressurized to keep pesticides out.
Key Structural Feature: The biplane design features four interchangeable outer wing panels, simplifying maintenance and reducing spare part inventory.
G-164C Specifics: This variant is distinguished by a further stretched fuselage to accommodate the larger 500-gallon hopper compared to the earlier A and B models.

Performance and Safety

Operating Speed: Typically 129 to 161 km/h (80 to 100 mph).
Stall Speed: Low stall speed, around 104 km/h (64 mph), critical for safe low-altitude maneuvering.
Rate of Climb: Approximately 329 m/min (1,080 ft/min).
Range: Limited ferry range (designed for short-range utility).
Safety Feature: The airframe incorporates a fuselage structure designed to progressively collapse upon collision, protecting the pilot.
Modern Upgrades: Many Ag-Cats have been upgraded over the years, often replacing the R-1340 radial engine with a turboprop (like the Pratt & Whitney PT6A) to create the Turbo Ag-Cat variants.
