1. 1 What Can be the alternate battery /power sources that
can be used in drones for higher endurance?
The U.S. military is looking for ways to improve the endurance of small unmanned aerial
systems using alternative power sources, said service and industry officials.
When using small drones which typically run-on lithium-ion batteries there are several
shortfalls that need to be overcome in order to make the systems more effective for war fighters.
“Typically what people want is greater range and endurance, basically being able to stay up
longer and fly farther. Additionally, “they want them to have greater onboard power.
OEPP is tasked with “maximizing the military capability we get out of energy while reducing
the burdens and risks that our energy supply lines create,” Jennings said. While the office
doesn’t solely focus on alternative power sources in order to achieve that goal, it is one of the
tools the Defence Department uses to squeeze every drop of energy out of its systems, he said.
The operational energy capabilities improvement fund (OECIF) is one of the ways the
department promotes technology that will improve operational energy performance. It
contributes science and technology research funding to several military projects and
encourages the services to take risks and move in new directions.
2 What is the impact on the alternate battery /power
sources that can be used in drones for higher endurance?
Drones are recently receiving a growing attention in both civil and military sectors. Despite
their good features such as high manoeuvrability, wide variety of usage, and low cost; battery-
powered drones are still limited in terms of endurance. They cannot perform long flights and
persistent missions. This paper proposes then a review-based discussion of the solutions
addressing this issue, including swapping laser-beam inflight recharging and tethering. Hybrid
power supply system is also a solution of choice. Combining battery with different sources
such as fuel cell, solar cells, and supercapacitor allows the system to benefit from sources
advantages and cover their limitations. In this context, this paper provides a comparative and
critical study of different power supply architectures, thus facilitating the trade-off in the choice
of the suitable drone power supply system. Insights and recommendations for future research
are also provided.
2. The Impact of Drones on Supply Chain Management. The estimated that drones and
other UAVs – unmanned aerial vehicles – could result in worth of economic growth. Drones
are receiving big interest from researchers in several domains. As the power supply system is
a fundamental unit in a drone platform, this paper has therefore dealt with comparative and
critical study on drones supplying sources and architectures. This review-based study aims
providing basis and insights about the choice of the appropriate power supply devices
considering sources features and flight requirements. It has also discussed supplying solution
for specific missions when battery-based drones have to operate continuously, namely
swapping, laser-beam inflight recharging, and tethered technologies.
