Jaxa announces the joint development of eVTOL with Yamato

According to akihabaranews, Japan Aerospace Exploration Agency (JAXA) and Yamato Holdings announced a partnership in the cargo compartment of electric vertical take-off and landing (eVTOL) aircraft. The two companies are collaborating to design and evaluate the aerodynamic shape of heavy and large PUPA 8801 pods

PUPA 8801 is a 400 kg payload class variant of the PUPA (pod unit for air transportation) series developed by Daiwa. The series can be connected to the existing ground transportation system of conventional load cells or installed from outside On the eVTOL aircraft.

In the process of ground transportation, the pod must follow the existing cargo unit size standards and be as rectangular as possible to maximize its function. If connected to eVTOL, the pod also requires high aerodynamic performance and is designed for fast loading and unloading. Therefore, PUPA 8801 must be innovative and different from traditional aerospace and logistics equipment.

With this in mind, JAXA provided “aeronautical expertise and used its high-speed fluid analysis tool FaSTAR to conduct a series of analyses based on computational fluid dynamics to improve aerodynamic efficiency.” Yamato manufactured a pod based on 100 years. Of ground transportation experience and research on freight eVTOL system.

FDG25 eVTOL

Flydragon FD-25 long endurance eVTOL wingspan 2.5 meters,it iss electric version . This model combines the characteristics of long-endurance, high-speed and long-distance of fixed-wing UAVs and the vertical take-off and landing of rotor-wing drones. It does not require runway but only small space for take-off and landing, and can be operated smoothly on ship deck, narrow airspace, mountain, complex terrain and densely populated areas such as hills, jungles. The whole process of autonomous flight can be completed without operator intervention for cruise, flight state transition and vertical take-off and landing. The equipment compartment is a replaceable hatch cover, and different mounting hole positions can be designed for different load requirements of the user. The fuselage is designed as quick release structure, with reliable electrical connection, plug and play; unfolding and withdrawal time is less than 10 minutes. The engine is rear-mounted and the load is placed forward to provide a larger field of view for the photoelectric load without obstruction.
