Measured drag agreement vs. wind tunnel at the yaw angles riders use most.

Decisions you can make

What can your team decide faster?

AeroCloud turns aerodynamic questions into evidence your team can act on - before committing track, wind-tunnel, or prototype time.

Rider position optimization

Compare CdA across race positions before committing track or wind-tunnel time.

Helmet & equipment testing

Screen helmet, wheel, frame, and apparel variants before physical prototyping.

Yaw sensitivity analysis

Understand how performance changes across realistic crosswind conditions.

Race setup comparison

Evaluate time-trial vs. road positions, skinsuit choices, and equipment combinations.

Development prioritization

Identify which changes deserve expensive wind-tunnel or track validation.

Validation & workflow

Wind-tunnel benchmarked workflow for sports aerodynamics.

Performance teams move from questions to validated designs in 4 hours. Your designers upload an STL, pick a sports scenario, and get a wind-tunnel-grade answer the same day.

  • Day one, your team runs it. No CFD hire. No training course. No tunnel slot.
  • Hours per answer. Drag, lift, yaw sweep, and pressure maps are ready to share.
  • Decision-ready results that help teams choose what to prototype, test, or race.
  • Validated against independent wind-tunnel testing. Reproduced the full CdA-vs-yaw curve across a ±15° sweep, within 2-3% at the angles riders spend most time in.

Built for your sports aerodynamics workflow

Whether your team is optimizing athlete position, developing faster equipment, or validating design changes before wind-tunnel time, AeroCloud helps you compare more options with evidence your team can act on.

Performance teams

Close the aero gap before race day by comparing position, equipment, and setup changes earlier.

Product development teams

Test more helmet, frame, wheel, and apparel concepts before committing to prototypes.

Research and innovation teams

Run repeatable aerodynamic studies across yaw angles, speeds, and design variables.

How it works

From performance question to design decision in three steps.

Import your geometry — AeroCloud interface
01

Import your geometry

Upload your STL or OBJ - rider, helmet, frame, or full setup - straight into AeroCloud.

Set up and run — AeroCloud interface
02

Set up and run

Set speed, yaw, boundary conditions and mesh quality, then hit run. Meshing and simulation happen in the cloud.

See the results — AeroCloud interface
03

See the results

Read drag, lift and CdA with 3D pressure, streamlines and slices - then compare variants and share the report.

Athlete-time calculator

Translate drag reduction into race impact

A small CdA change can decide whether a product change, position adjustment, or equipment choice is worth testing further. Use the calculator to estimate how aerodynamic gains may translate into time saved over a race distance.

This calculator provides decision-support estimates. Actual race outcomes depend on athlete power, course profile, weather, rolling resistance, equipment, and pacing strategy.

Definition

What is AeroCloud for sports aerodynamics?

AeroCloud is a cloud-based CFD platform for sports aerodynamics teams. It helps engineers and performance teams simulate airflow around athletes, equipment, and vehicles to compare drag, CdA, pressure, wake behavior, and yaw sensitivity before physical testing.
