Product overview
The Hongfei HBR T72 is an electrically powered agricultural spraying platform for large fields and fruit forests. Its eight-axis layout combines an integrated carbon fiber fuselage with aerospace aluminum structure. The payload specification is 72L/75KG, with a maximum takeoff weight of 147KG and a listed aircraft weight of 51KG. It measures 3920mm*3920mm*970mm, while arms that fold upward through 90 degrees reduce transportation volume by 50%. Airline-box packaging measures 2200mm*1100mm*960mm.
The spraying system provides a flow range of 8-15L/min, a specified working width of 8-15m and droplet sizes of 110-400μm. Spraying efficiency is 28-30ha/hour, alongside a flight-speed range of 1-10m/s and a flight-altitude limit of ≤ 20m. Integration centers on agricultural operation: GPS positioning, autonomous flight, terrain-following radar and front and rear obstacle-avoidance radar support route execution. Terrain-following sensitivity can be adjusted to suit different crops and terrain.
The power configuration pairs a 14S 42 000mAh lithium-polymer battery with a four-channel high-voltage smart charger capable of charging four smart batteries concurrently. Fully charged battery voltage is 60.9V; charging time is 30-40 minutes and battery life is 1000 cycles. Flight control integrates inertial and satellite navigation sensors. Plot, edge-sweeping and fruit-tree planning modes cover different spraying patterns; plot mode supports 128 waypoints with adjustable altitude, speed, obstacle-avoidance mode and flight path.
