- 空重
- 未公开／未录入
- 长度
- 未公开／未录入
- 翼展
- 未公开／未录入
- 高度
- 未公开／未录入
- 动力来源
- Lithium-ion battery recharged by a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) (a nuclear battery), at night. The battery takes 8 earth days to charge during the Titan night.
- 电机
- 8 electric motors
- 旋翼／螺旋桨
- 8 propellers
- 续航时间
- 30 minutes per charge
- 飞行高度
- 13,123 ft (4,000 m)
- 安全设计
- Distributed Electric Propulsion (DEP) means having multiple propellers (or electric ducted fans) and multiple electric motors on an aircraft so if one or more propellers (or electric ducted fans) or some electric motors fail, the other working propellers (or electric ducted fans) and electric motors can safely land the aircraft. DEP provides safety through redundancy for passengers or cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.
