Services / Test supervision and execution
Test supervision and execution, with the analysis behind each test
We combine analytical, numerical and experimental modeling. ATS plans the test, supervises it in the laboratory or in service, and compares the result with the simulation, to use fewer test hours and fewer prototypes.
Wind tunnel, PIV and certification tests, in laboratories such as IPT-SP, IAE and EESC-USP.
- Ship-helicopter envelopeOperating envelope of the Lynx helicopter on the corvette Barroso, with CFD++, wind tunnel and the Brazilian Navy.
- Fewer wind tunnel hoursCFD replaces part of the expensive wind tunnel hours, and the tunnel validates the CFD.
- Certification tests at IPTGas mixer tests for certification at IPT: two prototypes and two series heads.
- PIV at IAEParticle image velocimetry test at DCTA-IAE.
- Rigs and test plansDesign of test rigs and of the test plans for certification.
Complete projects, from the test plan to the report
We prefer whole projects to isolated services: ATS responsible for the analysis, the test plan, the supervision and the comparison.
Analysis before the test
Analytical and numerical models define what to measure and where, and reduce the number of tests.
Test planning and rigs
Test plan, instrumentation and rigs, including the ones for certification tests.
Supervision and comparison
Supervision of the test in the laboratory or in service, and comparison of the result with the simulation.

How ATS combines analysis and test
Three kinds of modeling
Analytical, numerical and experimental modeling are used together. Each one checks the others.
Why test
Tests validate the models and are required for certification. Simulation reduces their number and their cost.
In the laboratory and in service
ATS supervises tests in laboratories such as IPT-SP and in service, with the instrumentation defined in the plan.
Tools, and where each one fits
Tools serve the engineering work. We say what each one does in the project.
| Tool | Role in the project | Status |
|---|---|---|
| CFD++ | Fluid flow, heat transfer, combustion and particles in 3D. ATS is the exclusive CFD++ representative in Brazil. | Licensed |
| Tecplot 360 EX | Post-processing and automation macros, including erosion rate calculation. | Licensed |
Evidence you can check
Tests in laboratories and projects with the Brazilian Navy.

| Project | What we did | Tools and tests | Result or venue |
|---|---|---|---|
| Corvette Barroso: wind tunnel testProject | Wind tunnel test of the corvette Barroso, for the landing envelope of the Lynx helicopter. | Wind tunnel at EESC-USP, with Prof. Fernando Catalano. | Envelope of operation defined. |
| SHOL: CFD and wind tunnel dataProject | Ship-helicopter operating limitation envelope, with CASNAV. Model at scale 1/75, 11 measurement points, yaw steps of 9°. | CFD++ RANS, k-ε, 32.8 million elements, compared with the NLR low speed wind tunnel, at 30 m/s. | Fore-aft, oblique and cross-deck envelopes. CFD++ more conservative than the tunnel. |
| PIV test at DCTA-IAEProject | Particle image velocimetry test. | PIV at DCTA-IAE. | Test executed with ATS. |
| Gas mixer: certification tests at IPTProject | Tests of a gas mixer for certification. | IPT, with two prototypes and two series heads. | Tests executed for the certification. |

How an engagement runs
Diagnosis and goal
We define the problem, the operating conditions and the target with your team.
Model
The geometry of the equipment is prepared and the physics that apply are chosen.
Analysis
Numerical calculation based on the applicable physical principles.
Checks and validation
Results are checked for consistency and compared with tests, plant data or the literature.
Solution and report
Design of the solution, specification of the test when needed, and the report.
Follow-up
Support in the field test or in operation, and revisions.

Questions engineers ask before they hire us
Do you run the test or only supervise it?
Both. ATS plans, supervises and executes tests, in laboratories such as IPT-SP and in service.
Can the simulation replace the test?
It reduces the number of tests and of prototypes. Tests remain the way to validate the models and to certify.
Which laboratories do you work with?
IPT-SP, DCTA-IAE and EESC-USP, among others.
Do you design the test rigs?
Yes, together with the certification test plans.
Is our data kept confidential?
Yes. We work under NDA, and your design data and reports stay with you.
