1. Груман Г-164С Аг-Кат е вариант на Grumman G-164 Ag-Cat, едномоторен биплан селскостопански самолет, разработен от Grumman през 50-те години на миналия век. Ag-Cat е първият самолет, специално проектиран от голяма самолетна компания за селскостопанска авиация, и представлява значително подобрение в безопасността и надеждността в сравнение с преобразуваните прахосмукачки. Ag-Cat първоначално е произведен от Schweizer Aircraft по договор от Grumman, а по-късно и от други производители. Моделът G-164C е представен през 1995 г. от Ag-Cat Corp. и включва турбовитлов двигател Pratt & Whitney PT6A-34AG с мощност 750 к.с., по-голям капацитет на бункера, подобрена видимост на пилотската кабина и нов дизайн на опашката. G-164C Ag-Cat може да носи до 400 галона течност или 3000 килограма сухи химикали и може да работи от къси и груби полета. G-164C Ag-Cat се използва широко за запрашаване, пръскане, засяване и противопожарни операции по целия свят.

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.
