The present work focuses on assessing the potential of using NeoCASS for the preliminary sizing of conventional and non-conventional configurations, particularly for propeller-driven commuter and large regional transports. A survey on regional aircraft is carried out to identify the technological level on this category, and powerplant weight estimation relationships are proposed for both turboprop engines and electrical motors. A total of 20 representative regional aircraft are sized for the validation. A Comparison of the mass fractions results is made with respect to statistical guidelines, the main weight groups are contrasted with the actual data to quantify the estimation error, and correction models are proposed for the adjustment of the Operating Empty Weight for future implementations. Additional sizing for innovative distributed propulsion designs is presented, evaluating the impact in the structural weight when the number of engines is progressively increased and when the thrust fraction for the wingtip engines is modified.
As part of the graduates course in Flight Testing, I was responsible of planning, executing and analysing the results for the Phugoid and Level Acceleration flight test techniques on board of the ultralight aircraft G70. This short experience as flight test engineer opened my mind to the importance of proper planning and risks consideration during flight testing campaigns. Additionaly we also tested conventional takeoff and landing to validate the performance of the vehicle. For the analysis I developed an interface to animate the flight telemetry for data interpretation (Watch the video).
From the master's course of Wind Turbine Design, we did the preliminary design of an on-shore horizontal axis wind turbine of IEC Class 1B able to produce 2.6 MW of rated power , considering the aerodynamic, structural and control strategy aspects. Our team spent large effort in implementing a LQR controller and obtaining the proper gains to maximize the cost of energy (COE). The project involved mainly the analysis of steady performance, regulation trajectory, Campbell diagram, control system set-up, loads envelope and cost evaluation, using CpLambda code from PoliMI. (I also did the 3D model representation)
The RedLine project was a concept to develop a network of medical Unmanned Aerial Systems (UAS) to provide an efficient transportation of medical products between healthcare facilities, to save lives in times of critical shortage. The network functions include delivery of healthcare items urgently needed at critical access hospitals as a solution to the logistic challenges caused by poor transportation infrastructure, roads blocked by severe weather, natural disasters or traffic congestion. This idea was generated during the Technical Communication graduates course at Politecnico di Milano.
AidPlane was developed thanks to the IEEE Student Enterprise Award, an international prize offered by IEEE in 2015. The objective was creating a prototype unmanned aircraft able to carry medical goods and deliver them by means of a parachute system in remote areas. The same project was awarded the first place in the IEEE R9 RRR Regional Meeting held in Guayaquil-Ecuador in 2016. I was the leader of the project and the designer of the aircraft. The team was composed by engineering students from all branches, including aeronautical, mechatronics, multimedia and sound engineering.
I was Engineering and Technology Leader in the design, manufacture and test of the first prototype of hexacopter platform to deliver medical goods in remote areas in Cali, Colombia. I also contributed in the design of the ground control station for the same system. Together with the design team, we also developed a quadcopter for geology implementations using additive manufacturing for some of the components.
As part of the AIAA Student Branch, we participated on the DBF 20th version held in Wichita, KS. I was the leader of the design team and part of the manufacturing group. The objective was to develop an aircraft able to carry inside the components of another disassembled aicraft trying to resemble in a small scale the mission of large carriers like the Beluga or the Dreamlifter. We were among the best 20 design reports of the contest from which more than 120 teams registered. I learnt leadership, synergy and time/resources management.
As part of the AIAA Student Branch, we participated on the DBF 19th version held in Tucson, AZ. I was part of the design team, responsible for CAD design, advertisement and also I was part of the manufacturing process. I learnt teamwork, decision making, commitment and manufacturing skills.
I designed this model aircraft as part of the Aircraft Design Course during my bachelor. I was intended to carry a small glider on top and release it in flight. The airplane was able to flight perfectly without the payload, but with the glider I could not achieved a perfect take-off. I learnt that respecting the design requirements from the begining is essential for success in the design project. I was the design leader.
One of my professional experiences was with UAV design. I was responsible for 3D models and drawings, specially for the wing redesign and additional components like the gimbal to carry zoom and thermal cameras. I was also part of the team for flight mission planning in smaller UAV using Mission Planner software.
As part of the bachelor's Flight Dynamics course, I designed a hand-launched remote piloted aircraft aiming to verify the stability characteristics when using a stabilator configuration (all movable horizontal tail) instead of the conventional elevator.
As part of the bachelor's Conceptual Design course, I designed a machine for brakes and tires installation for the A320 family aircraft. The objective was to replace the traditional methods which use two independent machines which are not ergonomic for workers.
As part of my bachelor's internship I was Design Assistant for conceptual design and modeling of NDT modules frames used for aircraft engine parts. I did the drawing of some components required for the user manuals and the 3D model assemblies.
I was part of the AeroTech research group during my bachelor in which I was contributing in projects related to UAVs. In my first years I helped with the design of a ground control station for short range UAV. For my thesis I wrote a book chapter on the validation of aircraft performance for a specific mutipurpose UAV. The validation was made through experimental flights.
While learning CATIA V5 during the bachelor, my team and I did a 3D model for the Lycoming O320 using the Part Design, Surface Design, Assembly and Drafting modules.
Calima T-90 (Colombian air force training aircraft) cloud point processing and surface reconstruction using CATIA V5. The cloud point was obtained from 3D Scanner. The objective was to provide the external geometry to the team in charge of aerodynamic analysis.
