▪ Currently involved in Project Management activities of a 300 kg class low earth observation (LEO) satellite named as Pakistan Technology Evaluation Satellite, PakTes-1A.
▪ Carried out the detailed definition of all the phases of PakTes1A from mission planning, system engineering up to utilization phase.
▪ Conducted preliminary and critical design review (PDR/CDR) with PakTes-1A team at system/subsystem and unit level including all technical documentation/reports following European Corporation for Space Standardization (ECSS).
▪ Successfully headed a team of engineers to carry out design, analysis, development and vibration testing of the Qualification Structural/Thermal Model of PakTes-1A along with the housings of all subsystems.
▪ Carried out all the sourcing and executed procurements for the development of Structural/Thermal qualification model, whose structure is composed of honey comb sandwich material with embedded and surface heat pipes and other passive thermal control equipments.
▪ Successfully headed a team of aeronautical/mechanical engineers to conduct project management activities and design, development, installation and testing activities of an air born small aperture radar antenna (ABSAR) and housings for its support electronics on a small aircraft.
▪ Implemented a comprehensive quality assurance program as configuration control board member at different phases of projects with the coordination of Product Assurance team, reviewing technical accuracies, incoming materials and assemblies, test procedures, MIPs/KIPs etc.
▪ Thoroughly participated in the Project Management activities for the development of customer furnished instruments (CFIs) of PakSAT-1R (a geostationary communication satellite of Pakistan) from mission definition, system engineering up to utilization/launching phase.
▪ Participated in project monitoring activities of Ground Control Segment of PakSAT-1R developed by CAST, China at Karachi, Pakistan.
▪ Monitoring and implementation of quality assurance processes and procedures defined by Product assurance team for different phases of projects.
▪ As a lead structural/thermal engineer performed the activities of thermal and mechanical design, analysis, manufacturing and testing of the housings/boxes of several customer furnished instruments (CFIs) which are installed in PakSAT-1R and functioning successfully in-orbit.
▪ Designed and analysed structural configuration at system level as per the mission requirement including the design and analysis (based on rib stiffening system to achieve higher natural frequency) of several housings/boxes for electronic subsystems such as power, AOCS, OBC/OBDH, payload, TMTC modules for PakTes-1A.
▪ Performed thermal design and analysis at all stages of satellite design. Built all thermal models (main Space Vehicle model, all box-level, and all board-level models), evaluated environmental considerations, selected all emissive coatings, and provided feedback to mechanical and structural designs.
▪ Headed the design and development of a solar panel deployment mechanism based on torsion spring hinge and thermal knife for latching for the qualified model of a PakTes-1A.
▪ The aim of this work was to predict the cyclic behaviour of AISI H11 tool steel with a nominal Rockwell Hardness of 47. Various isothermal and non isothermal conditions have been investigated with different strain rates, strain amplitudes and temperature levels, by applying two different approaches. A constitutive thermo-elastoviscoplastic model was considered which includes kinematic and isotropic components to define strain rate effects, dynamic recovery and cyclic softening.
▪ To progress further, two types of loading conditions (variable temperature and variable strain amplitude) had been designed. A test bench had been developed to conduct these experiments and a complete time-temperature-strain history is presented further in terms of applications of these models and to observe the behaviour of the material under complex loading.
▪ In accordance with the experimental data base, these behaviour models had been characterized and analyses of their pertinence and limitations had been carried out in order to upgrade them to satisfy different working conditions.
▪ Finally, numerical simulation on a structural thermomechanical fatigue test specimen had been performed by using these constitutive laws to analyse their applicability under severe loading conditions.
▪ Submitted and defended the PhD dissertation with honors in Albi, France, in front of an international jury composed of a professor from Karlstad University Sweden, a professor from Ecole Polytecnico di Turino Italy, along with other professors from France.
▪ Participated in the design and fabrication of a prototype satellite structure based on honey comb sandwich panels. One-shot fabrication technique was used and sine sweep testing was performed to validate the fabrication criteria.
▪ Conducted compressive strength testing of honey comb sandwich panels to determine in plane and out of plane compressive strength. These tests were performed on aluminum and glass fiber panel facings in order to compare their mechanical properties.
▪ Trouble shooting and maintenance of a space simulator/humidity chamber.
▪ Development of a mechanical work shop, procurement of different machines e.g. lath, milling, shearing and drilling etc.
