I used DeepSeek to analyze an interesting problem.
If we use C200 UHPC to build a reinforced hangar, assuming the engineering structure is reasonable, how thick does it need to be to withstand a direct hit from a BrahMos missile?
Note: UHPC stands for Ultra-High Performance Concrete. C200 is the highest grade of UHPC currently available. Its compressive strength reaches 200 MPa.
DeepSeek gave me the answer:
A three-layer composite structure is recommended for the hangar.
Outer layer: 0.3-0.5m C200 UHPC
Middle layer: 0.2-0.3m buffer layer (can be made of foamed concrete or steel)
Inner layer: 0.7-0.8m C200 UHPC reinforced with steel bars
Total thickness: 1.2-1.6m
If a single-layer structure is used, its thickness needs to be at least 1 meter, but the safety factor is not as good as that of a three-layer composite structure.
This analysis is based on the basic parameters of the BrahMos missile, namely a flight speed of Mach 2.8-3 and a 200-300 kg high-explosive warhead. Both kinetic and explosive impacts are calculated. If the BrahMos missile's parameters are improved, this analysis will also improve.
