Aarush-M is the smaller version of Aarush-X1, was designed by the team for participation in AUVSI SUAS '13, the annual student unmanned aerial system competition held annually in Maryland,USA. Aarush-M is a twin-boom, inverted V-tail UAS designed for delivering situational awareness in a disaster struck area. Command and control over UAS is done via a 2.4 GHz radio link, while the intelligence gathered is transmitted over a 5 GHz link. A highly modular and portable system, Aarush-M can be flight ready in less than 30 minutes, providing an endurance of 20 minutes.
Aarush-M is a twin boom inverted v-tail pusher aircraft with a wingspan of 122” and having an empty weight of 32 lbs.. The airframe has been designed and fabricated by undergraduate mechanical engineering students of the team. It is powered by Hacker A80-8 electric motor with a 22x8 propeller. A single axis gimbal for the camera has been integrated with the system, to provide +/- 45 degree roll compensation.
One of the ancillary objectives of the team was to develop a robust aerial platform fit for indigenous research, besides performing in SUAS ‘13. The fabrication process for the new airframe was carried out completely in the UAS-DTU lab at DTU. The fuselage features a monocoque shell design composed of carbon fiber/epoxy sandwiching balsa sheet for additional stiffness. Sandwiched laminates of carbon fiber, glass fiber and balsa sheet were made for testing and experimentally determining their strengths which would be further used for wing and tail skins. As a result 200 GSM glass fiber (45 degrees) and balsa sheet were used. The design features twin CF booms and solid spring CF landing gear. Landing gear, wing & tail skins were manufactured using CNC cut medium density fiber molds. The wing assembly consists of two outboard sections and one mid-section.
Aarush-M was indigenously fabricated over a period of 3 months followed by 5 weeks of rigorous flight testing making the UAS flight ready for the competition.
Suas '13 was held from 19-22 June 2013 where 35 teams competed. Aarush-M bagged the team 6th position in the competition.
