This paper describes the integration and test work of a small unmanned aerial vehicle (UAV) with autopilot capability, which is currently being developed at New Mexico State University. The UAV is an integration of a commercially available autopilot system (Micropilot’s MP2128HELI) with an RC helicopter (Raptor 90). It has been found quite challenging to integrate an autopilot system with a hobby RC helicopter for research purpose because hobby airframes, as low-cost and manually operated toys, were not designed readily for working with delicate and sensitive autopilot electronics. In our case, the strong vibration disturbances from the gas engine and other moving parts of the airframe significantly corrupted the signals from the avionics hardware. Innovative vibration isolation technique has been developed to mechanically isolate the vibrations from affecting the autopilot system. Several other key problems related to electromagnetic interference shielding and safe flight test were also effectively solved on the project. The integration work has been completed and the UAV is currently being tested.

Unmanned Aerial Vehicle (UAV) is becoming increasingly popular because it can perform variety of functions. These functions include surveillance, reconnaissance, monitoring, data collection and rescue operation. The purpose of this work is to design, fabricate and fly a low weight, low cost, small size UAV for a surveillance mission. The design is carried out based on Advanced Aircraft Analysis (AAA) software. The design process starts with the design specifications for a typical surveillance mission. Aircraft weight, wing loading and power loading were estimated in performance sizing process. Geometry was estimated using preliminary sizing. Aerodynamics of the aircraft was determined, which enabled the performance and stability to be analysed. If the desired performance is not achieved, the sizing is readjusted until a final design is reached. The aircraft was manufactured using foam, carbon rods, and fibreglass. The aircraft successfully flew at the first trial flight. This was followed by a successful flight with aerial photography.

This research will try to design a low cost of fixed-wing unmanned aerial vehicle (UAV) using low-cost material that able to fly autonomously. Six parameters of UAV’s structure will be optimized based on basic airframe configuration, wing configuration, straight wing, tail configuration, fuselage material, and propeller location. The resulted and manufactured prototype of fixed-wing UAV will be tested in autonomous fight tests. Based on the flight test, the developed UAV can successfully fly autonomously following the trajectory command. The result shows that low-cost material can be used as a body part of fixed-wing UAV.

Studying the biological processes of wildlife and how they react and prevail with human population growth and development has become very important to sustain species and prevent extinction. Wildlife tracking has become a very important tool in this matter by giving researchers an idea of animal territory and habitat. However, the process of finding the animal after it has been tagged can be very tedious and costly. To make this tracking process more efficient, researchers at Utah State University (USU) are developing a low cost RF telemetry system for wildlife tracking using an autonomous Unmanned Aerial Vehicle (UAV) for triangulation and geo-location of the target. The use of small unmanned aircraft systems (UAS) for wildlife tracking offer many advantages such as cost reduction, human effort reduction and data acquisition efficiency due to the usage flexibility offered by the system in comparison to conventional methods. This paper presents the design of this tracking system, and shows some experimental data.

AbstractBiomass-derived materials have recently received considerable attention as lightweight, low-cost, and green microwave absorbers. On the other hand, sulfide nanostructures due to their narrow band gaps have demonstrated significant microwave characteristics. In this research, carbon microtubes were fabricated using a biowaste and then functionalized by a novel complementary solvothermal and sonochemistry method. The functionalized carbon microtubes (FCMT) were ornamented by CuCo2S4 nanoparticles as a novel spinel sulfide microwave absorber. The prepared structures illustrated narrow energy band gap and deposition of the sulfide structures augmented the polarizability, desirable for dielectric loss and microwave attenuation. Eventually, the architected structures were blended by polyacrylonitrile (PAN) to estimate their microwave absorbing and antibacterial characteristics. The antibacterial properties against Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus) were scrupulously assessed. Noteworthy, the maximum reflection loss (RL) of the CuCo2S4/PAN with a thickness of 1.75 mm was 61.88 dB at 11.60 GHz, while the architected FCMT/PAN composite gained a broadband efficient bandwidth as wide as 7.91 GHz (RL > 10 dB) and 3.25 GHz (RL > 20 dB) with a thickness of 2.00 mm. More significantly, FCMT/CuCo2S4/PAN demonstrated an efficient bandwidth of 2.04 GHz (RL > 20 dB) with only 1.75 mm in thickness. Interestingly, FCMT/CuCo2S4/PAN and CuCo2S4/PAN composites demonstrated an electromagnetic interference shielding efficiency of more than 90 and 97% at the entire x and ku-band frequencies, respectively.
