Shell Optimisation

Fig:1

Structural Simulation of Hyperloop Shell

Aim: To design a composite body with optimised fibre orientation for optimum weight and structural stiffness.

Layup Sequence - [0/45/90/core/90/45/0]
Material - GFRP, core – Polyurethane Foam
Thickness varies from 4.2 mm to 1.2 mm
Boundary conditions:
1. Drag Force 
2. Self Weight
3. Deceleration
4. Levitation Force 
20% reduction in weight achieved

numerical and experimental study

Full-Scale Study and Turbulence Model Validation

Aim: To validate the numerical technique for full-scale study

1. k-omega SST Turbulence Model
2. Inlet Mach: 0.43
3. Blockage Ratio: 38%
4. 1000 samples were taken from each port and averaged for more accuracy. 
5. less than 3% error

Heat transfer enhancement
