Group Design Project: ‘Mission to Titan’
The purpose of this project was to design mission to the Saturnian moon Titan which is of great interest to the planetary science community, due to its atmosphere, presence of organics, and the occurrence of many analogs of terrestrial processes and phenomena. This mission suggested the use of an orbiter, lander, lake vehicle and airship to investigate the different science aspects mentioned earlier. I was responsible for structural analysis of both lander and lake vehicle. Working within a team of eighteen, the project involved regular meetings every week, detailed planning of the work process, project monitoring and reporting.

Sept 2004-Sept 2008
Aeronautical Engineer, Aeronautical Division
· Performed static and dynamic analyses, free vibration response, modal analysis and transient analysis of the aircraft structures and other mechanical systems.
· Analyzed models after extracting modal parameters of a system (resonance frequencies, damping, and modal shapes) from real measurements.
· Visualized the dynamic behavior of the tested structure.
· Estimated the structure behavior depending on modifications of the structure or of the solicitations.
· Performed simulation, organized and scheduled experimental test for data acquisition, processed the data and analyzed the results acquired, prepared the test report, wrote the paper for publication and presentation at conferences.
· Benchmarking of finite-element analysis and experimental results.
Project participation included:
Tandem two-seat primary/basic trainer LASTA-95(first flight February 2009)
· Responsible for the specification and control of aileron, tailplane, elevator and rudder torsional stiffness tests. Conducted FE meshing and analysis using MSC Patran/Nastran to model the load cases for static testing. Attended and monitored the tests to ensure that the test conformed to requirements. Issued official reports and specifications.
· Used IDEAS to design 1:5 scale wind tunnel model of the trainer. Conducted its FE analysis and simulation. Performed modal analysis and compare it with finite element analysis. Issued the official report.
· Used hand calculations to find natural frequencies of control system. Performed its FEA and simulation using IDEAS. Performed stick force analysis for steady state straight line flight. The effect of trim tabs was also considered.
Unmanned Air Vehicle (UAV) TD
· Investigated vibrations on UAV and its effect on the various components of the UAV. Modal analysis and frequency response analysis has been carried out for some of the components to find natural frequencies and displacements for the given excitation levels. During take-off, engine imparted high loads into sensitive UAV components. Each of these components and subsystems had to be designed to withstand these vibrations. To make components strong enough to withstand these loads required additional weight, which would increased costs and reduced overall performance. A better option was to reduce the magnitude of the vibrations into the sensitive components by carefully designing vibration isolation system for which I was responsible.
Assault transport helicopter
· Conducted vibration measurements, time and frequency response analysis during take-off and some maneuvers. Purpose of this examination was vibration monitoring and evaluation of pilot exposure to whole body vibration.
Civil trade ship “Deligrad”
· Performed measurement on trade ship of length 95m, width 11m, height 3.2m and carrying capacity of 1850t with two main and one auxiliary engines (Caterpillar) and one in bow. The responsibilities included vibration measurements with B&K Pulse 3560D Multichannel Portable Data Acquisition Unit in engine room, saloon, cabin and pilot house by given sailing regulations. Processed vibration signals instantly in frequency and octave analyzer. Compared these vibrations with allowable ones defined with ISO 6954, ISO 2631 and ISO 10816-3 standards.
Military ship
· Performed vibration measurement and analysis same as with civil trade ship. Issued official report and specifications.
