About Zunain

I did not fall in love with engineering in a classroom. I fell in love with it the first time a simulation I built matched reality.

I am an aerospace and avionics engineering student, and alongside my degree I work as a freelance simulation engineer running CAD, CFD and FEA projects for real clients through my own engineering practice, Simvionix Engineering. That combination is the whole reason I tutor well: I am close enough to being a student to remember exactly which line of the derivation broke you, and far enough into real projects to show you why that line matters.

Here is the work behind the subjects I teach.

In AERONAUTICS, I have taken a tailless blended delta-wing UAV from a blank page through full preliminary and detail design — sizing, aerodynamics, stability, structures. I have run ANSYS Fluent CFD on complete UAV geometries at cruise, and on fin-stabilized projectiles through drag-coefficient sweeps. When I explain a drag polar, I am explaining a curve I have generated myself.

In PROPULSION, I have carried out thermal and CFD analysis on a coaxial methane/LOX injector head, chasing down face-plate overheating, and heat analysis on rocket nozzles in RPA. I have processed real LN2 cold-flow injector test data — discharge coefficients, pressure drop, spray cone angles. Combustion and nozzle theory is not abstract to me. It is a dataset I have argued with.

In SPACE SYSTEMS, I have designed a CubeSat structural frame in CATIA V5 — skeletonized panels, deployable solar arrays, thruster cluster. Satellite subsystems make far more sense once someone shows you the actual hardware they were derived from.

In CONTROL and ROBOTICS, my final year project is a full digital twin of an F450 quadcopter built on ROS2, PX4 and Gazebo, running the same control stack in simulation and on the real airframe. Controllers, state estimation, sensor fusion, tuning — I have debugged all of it at 2 a.m. with a drone on the bench. That is the experience I bring to your PID assignment.

HOW I TEACH

Patiently. I do not lecture at you.
I ask what you already know, find the exact gap, and build from there.
I use diagrams, physical intuition and simulation before equations — because equations you cannot picture are equations you cannot recall under pressure.
I am direct about mistakes and generous with encouragement, and I never make a student feel slow for asking twice.

WHAT I ALSO OFFER

Full support on final year projects, capstones and senior design — from concept and CAD to CFD, FEA, results and the written report. I have taken multiple projects end to end, so I know where they usually stall.

WHERE I TEACH

Online, worldwide. I work regularly with students across the United States — California, Texas, Florida, Massachusetts, Georgia — and I schedule around US time zones without complaint.

If you are struggling in aeronautics, robotics, space systems, control or propulsion, message me with your course outline and your deadline. I will tell you honestly whether I can help and how fast.

About the lesson

Every student who books me arrives with the same sentence: "I understand it in the lecture, but I freeze on the exam."

Let me tell you how we fix that.

We start with AERONAUTICS. Not with a slide deck — with a wing. You will see why a wing lifts, where the boundary layer separates, why your drag polar bends the way it does. Once aerodynamics stops being a formula sheet and starts being a picture in your head, the numbers finally behave. I cover lift and drag, airfoil theory, compressible flow, shock waves and aircraft performance, with full aerodynamics homework help and exam prep.

Then we open the engine — PROPULSION. Turbojets, turbofans, ramjets, solid and liquid rocket motors. We walk the gas through the cycle stage by stage: intake, compressor, combustor, turbine, nozzle. I have run real injector and nozzle thermal analyses, so when we talk about chamber pressure, specific impulse or nozzle expansion ratio, it comes from work, not just from a textbook. Rocket propulsion, jet engine cycle analysis and thermodynamics are core lesson territory.

Next we go up. SPACE SYSTEMS. Orbital mechanics, Kepler's laws, Hohmann transfers, delta-v budgets, attitude determination and control, CubeSat design and satellite subsystems. Most students find orbital mechanics terrifying until they see one clean diagram. We draw that diagram in lesson one.

Then we make it stable — CONTROL SYSTEMS. Transfer functions, root locus, Bode plots, PID tuning, state-space, MATLAB and Simulink. This is where the highest marks are lost and where I have seen the fastest grade recoveries. We build your intuition first, then your MATLAB code, then your exam speed.

And finally we make it move — ROBOTICS. Kinematics and inverse kinematics, dynamics, path planning, sensor fusion, ROS/ROS2, Gazebo simulation, Arduino and drone control. I have built and flown quadcopter systems with PX4 and ROS2, so robotics lessons here are hands-on: you leave with something that actually runs.

HOW THE LESSON RUNS

Online, one-to-one, screen shared, camera on if you prefer.
I solve, you solve, then you teach it back to me. That last step is the one that survives exam day.
Every session ends with a short practice set and a clear next step.

WHO I TEACH

University students in aerospace, mechanical, mechatronics and electrical engineering
Students stuck on a semester course, a lab report or a coursework deadline
Final year project and capstone / senior design students who need real CFD, FEA or simulation guidance
High school and first-year students entering robotics competitions or STEM programs
Graduate students preparing for qualifiers and thesis defense

TOOLS WE CAN WORK IN

ANSYS Fluent, ANSYS Mechanical, MATLAB, Simulink, SolidWorks, CATIA V5, ROS2, Gazebo, PX4, XFLR5, RPA, Python

The first lesson is a diagnosis. Bring your syllabus, your worst topic and your next deadline. We will build the plan from there.
