About me

Fourth-year Aerospace Engineering student at Universidad Carlos III de Madrid and TU Delft, with an 8.0/10 academic average and honours in Thermodynamics, Avionics, Physics, and Technical Drawing, a discipline that began with a regional win at the Cantabria Technical Drawing Olympiad.

Every technical course I complete propulsion, computational fluid dynamics, control theory, flight mechanics becomes a complete, documented analysis, often within international teams assembled in a second language. The same habit extends beyond the transcript: a clothes brand co-founded with friends, watches assembled by hand and sold on commission, and a drone pilot licence earned simply to see the industry from another angle.

Nova Electric Racing

Nova Electric Racing is TU Delft's student team behind fully electric racing motorcycles, European MotoE Cup champions, drawn from more than half a dozen nationalities and engineering disciplines.

I joined during my Erasmus semester in Delft, working alongside mechanical, electrical, and project management students under competition deadlines. When the semester ended, I continued contributing remotely from Spain through the second term, coordinating deliverables at a distance with the rest of the team.

Within Nova, I worked in the Partnerships & Media department, securing and managing sponsorships with technical partners including Ansys, EasyComposites, Altium, RS Components, and Würth Elektronik, while rebuilding the team's website and driving its presence on Instagram and LinkedIn. We also represented the team at industry events across the Netherlands, including Motorbeurs Utrecht, the Technology Track in The Hague, and Tech Beach in Tilburg.

The role crossed into engineering as well. Once we secured the Ansys licences, I trained the Aerodynamics department on Ansys CFD, applying my Aerospace Engineering background directly to their workflow. None of this paused when I returned to Spain, sponsorship, media, and technical support continued remotely alongside the rest of the team in Delft.

This is evidence that I can integrate into a technical team already in motion, in a second language, and that my commitment does not depend on sharing a building with the rest of the team.

Case Studies

Some projects from my coursework at UC3M and TU Delft.

CFD Analysis of an Airfoil Near Stall

CFD for Aerospace Engineers — TU Delft · Team assignment

2D RANS simulation of a NACA0012 airfoil at high Reynolds number across three angles of attack, with the emphasis on verifying the numerics before trusting the aerodynamics. A refined mesh reaching y+ < 1 was compared against a coarser one, and a first-order discretisation scheme against a second-order scheme with an EARSM turbulence model.

  • First-order scheme underpredicts lift and overpredicts drag via excess numerical diffusion
  • Refined mesh + EARSM results matched experimental reference data closely

Aircraft Stability & Performance

Mechanics of Flight I — UC3M · Group assignment

Two linked problems: the equilibrium of a spring-loaded rudder relative to the aircraft's centre of mass, classified analytically via the eigenvalues of the system's Jacobian; and the performance of a full aircraft in cruise and sustained turning flight, integrated numerically in MATLAB (ode45) and Simulink for three initial velocities and validated against the analytical dimensionless model.

  • 5h simulated turn at constant bank angle
  • Weight loss from fuel burn produces a spiral of increasing radius, despite constant bank angle

Engineering a Next-Generation Turbofan

Aero Engine Technology — TU Delft · Team assignment

Cycle analysis of a geared turbofan in cruise, paired with the sizing of a real combustion chamber (Rolls-Royce Trent XWB-84) under a Rich-Quench-Lean strategy to minimise NOx. Stagnation properties were modelled station by station and coded in MATLAB; the combustor's airflow was split across rich, quench, and dilution zones to meet turbine inlet temperature targets.

  • 25.44 kN total thrust, at an SFC of 16.92 g/(kN·s)
  • 31.6% overall thermal efficiency
  • 51.1 L combustor volume, cooling gas from 2,282 K to 1,688 K before the turbine

Control System Design for a Carrier Landing

Aerospace Control Systems — UC3M · Individual assignment

A fighter aircraft correcting its lateral position on carrier approach is modelled with an unstable open-loop pole. The pilot's response was modelled as a PI controller, and the exact gain range that keeps the closed-loop system stable was derived with the Routh-Hurwitz criterion, then cross-checked against Bode diagrams and the time-domain response. A second part extends the same toolkit to nonlinear elements like saturation, hysteresis and dead zones using the Describing Function method, the Nyquist criterion, and phase-plane analysis.

  • K Stable for 59.07 < K < 209.93
  • Outside that window: divergence (passive pilot) or growing oscillation (over-correction)

Personal Proyects

Hobbies and interests

Small Startup · 2021

A clothes brand, four co-founders

Teamwork · commercial judgement · product launch

Co-founded a small apparel brand with friends. Design, production, and sales, from concept to paying customer. From this I have learned that launching proyects with others requires fast agreement and accepting the first version is never final.

Watches, assembled by hand

Attention to detail · self management · patience

Hand assembled and sold watches, from the movement to the strap, with no one reviewing the work before the client did. This proyect taught me that details and precision are not optional.
