Selected cases in design, simulation, validation and aerospace development.

01CFD · AERODYNAMICS

Stratospheric lifting body

Aerodynamic validation of an unpowered descent vehicle from 22 km, designed to protect a scientific sampling probe.

22 km3 scenariosTransient flow

ANSYS Fluent analyses at 103, 40 and 9 kPa. The pressure distribution confirmed descent stability, vertical stabilizer control and payload compartment isolation.

CFD flow simulation over the stratospheric lifting body — 01Flow field · Transient aerodynamic validation

Velocity vectors around the lifting body — 02Velocity vectors · Descent stability

02FEA · STRUCTURES

Aircraft panel repair

Structural validation of a riveted repair patch on an aluminum aircraft skin panel under static operational loads.

0.003754 mm5.061 MPaIntegrity validated

Mesh refinement at stress concentrations and load-transfer assessment across the panel, internal stringers and rivet pattern; stresses remained below yield strength.
