Product overview
The Doosan Mobility Innovation DJ25 is a hydrogen fuel cell VTOL aircraft for long-distance inspection and large-area surveying and mapping. Its airframe measures 2.1m in length and 4.4m in span, with a maximum takeoff weight of 31kg and maximum payload of 4kg. Flight time is 330min with payload, while the 450KM flight-distance figure applies at an average speed of 25m/s. Economical cruising speed is 22m/s. Maximum altitude is 3,500m, and wind resistance is specified as 10.8 ~13.8 m/s.
Mission payload options include the MG-202 monitoring system with 50x lossless photoelectric zoom and infrared cameras, the CA102 42.4 MP full-frame aerial camera, the IXM-100 medium-frame industrial camera, and the CA503 210-million-pixel full-frame tilt camera. Control choices include a handheld tablet, portable ground station, and vehicle-mounted/base ground station. The power module system weighs 7kg with a 12L Type 3 cylinder or 8kg with a 10.8L Type 4 cylinder. Tank replacement takes 30 seconds when using DMI's hydrogen tank refueling and delivery service.
