A multi cycle propulsion system for amphibious unmanned aerial vehicle with repeatable water exit
In view of the overall scheme and mission requirements of an amphibious unmanned aerial vehicle (UAV) with repeatable water exit
a multi‑cycle propulsion system using pump for water jet propulsion underwater
liquid rocket engine propulsion for water exit
and turbofan engine propulsion for air cruise was proposed.According to the development status and trends of propulsion system technology
the characteristics of different engine cycles
the thrust requirements of each stage and the requirements of multi‑cycle tasks
the study of multi cycle program design methods was carried out
and the typical propulsion system program size
mass
mission profile fuel consumption quality
etc
were calculated.The feasibility of the multi cycle propulsion system scheme and its design method were verified.The results showed that the multi cycle propulsion system scheme designed can meet the repeatable water demand of the unmanned aerial vehicle
in which the energy demand could account for about 26% of the total mass of the whole aerial vehicle.
