CFD: Grid Generation
•Two girds were generated using MATLAB (Delaunay Triangulation) and FORTRAN (for Cartesian Grid). Along with the Panel Method code (MATLAB) to solve the potential flow over NACA 0012 airfoil section.
•Second code was written based on Lifting Line theory, in MATLAB, to solve the Potential Flow over entire wing section.

Hess-Smith Panel Method for
Velocity and Pressure calculations
Piper PA-28 Instrument Panel Design
Six Primary Instruments were
modelled in MATLAB. All
instruments were programmed
with the fully functional
keyboard interface, and a
detailed flight dynamics model
running stored in Simulator’s
library.
All instruments were modelled
with ‘on board’ warnings such as
Stall, speed limits and structural
limits, and digital displays for
Mach number, Climb Rate, and
altitude.
Only Heading Indicator was not
modelled
Landing Simulator (C++/OpenGL)
Almost all of the modelling was done on LINUX operating system, using C/C++ and OpenGL Libraries.
Currently I am working to enhance the simulator to develop a detailed Instrument panel for A340, using C, OpenGL, and Adobe Illustrator
Skills Gained: Programming, Linux Operating System, 3D modelling using OpenGL, Animating using OpenGL, Vector Graphics, and Adobe Photoshop
Optimisation: Genetic Algorithms
Optimisation Techniques: Single and Multi VariableEvolutionary Algorithms (Genetic and Particle Swarm)Gradient Methods, Conjugate Gradient and Newton’sMainly for structural optimisation constraint and unconstrained Performed in MATLAB

Simulation Fidelity Assessment
MSc Thesis:
Assessment of fixed wing aircraft simulator fidelity, based on the pilot-vehicle system. Set of data obtained from simulated and flight test landing flare manoeuvre for Jetstream 31 aircraft.
Piloting Control Strategy was developed based on the dynamics of Lead-Lag Network. This was done to distinguish the dynamics associated with the execution of a task from those of the pilot, per se. Analysis was based on Parameter Identification Techniques (In Frequency Domain), Least-Square Identification, Time Histories, and Phase Plane Trajectories of the flare manoeuvre.
System Identification Techniques were used, in conjunction with Handling Qualities Engineering, to quantify and characterize the overall response of the system (aircraft). MIL-1797A, JAR-FSTD 1A, JAR-25 and JAR STD standards were used throughout the project.

Blogging
Fascinated by Journalism, I started blogging and actively enhanced my web presence. I not only share my knowledge with others, but I love to talk about current affairs, sports and some interesting stories in Aviation Industry.

Reading: Some of my Best Reads
I have a strong obsession of Reading and Coffee, which have enabled me to setup my personal small library, which includes Fiction, History, Politics, and Military History books. I love Tom Clancy, Simon Scarrow, and Fatima Bhutto. My biographies collection includes Napoleon, Lord Wellington, Admiral Nelson, Mao Tse Tung, and Nelson Mendela.
Photography
I am doing photography since I was 13, and competed in many Competitions and participated in many Exhibitions. I have participated in two Exhibitions run under the Govt. of Pakistan (Ministry of Tourism) and other under World Wild Fund (WWF) Pakistan. I have a keen interest in Architectural Photography, Portraits and Macro Photography My Rig:
