Hi, I'm Tejas L πŸ‘‹

Aerospace Engineering β€’ Orbital Mechanics β€’ CFD β€’ FEA Automation β€’ Propulsion

I'm a final-year Aerospace Engineering student at RV College of Engineering, Bengaluru, working across orbital mechanics, computational fluid dynamics, structural meshing automation, and propulsion system design and test.

I try not to stop at the simulation β€” every project here goes from theory to a build, a test rig, or a working script.


πŸš€ What I Work On

πŸ›°οΈ Aerospace Systems & Orbital Mechanics

  • LEO constellation orbital propagation (SGP4/HPOP) and conjunction/collision-risk analysis
  • Satellite subsystem-level modeling within larger interdisciplinary systems
  • Interest in space situational awareness and collision-avoidance strategy

🌬️ CFD & Aerodynamics

Tools: ANSYS Fluent Β· ANSA Β· SolidWorks Flow

  • Compressible / supersonic flow β€” oblique shocks, shock–boundary-layer interaction
  • Propeller and rotor aerodynamics (blade element momentum theory, thrust/drag prediction)
  • Solver validation against benchmark cases before trusting a new geometry
  • Slosh and internal-flow analysis for fuel systems

πŸ”§ FEA & Simulation Automation

Tools: BETA CAE ANSA Β· Python (OOP scripting)

  • Scripting commercial FEA/meshing tools instead of clicking through them by hand
  • Mesh-quality-controlled, batchable pipelines for mesh-convergence studies
  • Turning one-off analyses into repeatable, logged workflows

πŸŒ€ Propulsion & Powertrain

  • Variable-pitch propeller design: blade theory β†’ CAD β†’ CFD β†’ 3D-printed prototype β†’ test rig
  • Formula Student fuel and dry-sump oil tank design, cross-validated against two independent sizing methods
  • Interest in the full loop: design β†’ predict β†’ build β†’ measure β†’ compare

⚑ Controls, Instrumentation & Embedded Systems

Tools: MATLAB Simulink Β· Arduino

  • Block-diagram modeling of full sensor-to-actuator signal chains (pressure regulation, 4–20 mA sensing)
  • Custom test-rig instrumentation: non-contact RPM sensing, thrust measurement, serial data acquisition
  • Optical wireless communication (Li-Fi/VLC) prototyping across two hardware generations

πŸ“š How I Approach a Project

Problem / Requirement
        ↓
Analytical Model (first principles)
        ↓
CAD / Simulation (CFD, FEA, Simulink)
        ↓
Automation & Scripting (where the workflow repeats)
        ↓
Physical Prototype
        ↓
Experimental Test & Measurement
        ↓
Compare Predicted vs. Measured β†’ Engineering Conclusion

I care less about "did the simulation run" and more about does it hold up against a benchmark case, a test rig, or a second independent method β€” that comparison shows up somewhere in most of the projects above.


πŸŽ“ Interested In

Turbomachinery Design Β· Gas Turbine Engines Β· Systems Engineering

CFD Β· FEA & Simulation Automation Β· Instrumentation

Hands-On Hardware & Mechanical Design Β· Design for Manufacturing (DFM) Β· Engineering Innovation

I'm drawn to problems that sit at the intersection of these β€” turbomachinery and gas turbine systems in particular, where aero-thermal simulation, structural analysis, manufacturability, and physical test all have to agree with each other before a design is actually good. That's the same loop I keep coming back to across the projects above: model it, automate the repetitive parts, build it, and check the hardware against the prediction.


πŸ”­ Where I'm Headed

Beyond the projects above, I'm actively building toward:

  • Design Automation β€” scripting CAD/CFD/FEA workflows (in the spirit of the ANSA meshing project) so engineering iteration cycles get faster, not just individual analyses
  • Machine Learning for Aerospace Design β€” using data-driven models to speed up or supplement traditional simulation, especially in design-space exploration and optimization
  • Data Analytics in Aerospace Engineering β€” extracting engineering insight from test and simulation data at scale, rather than one-off manual post-processing

The common thread: less time spent re-running the same analysis by hand, more time spent on the engineering decision it's meant to inform.
