Nice wall, but will it blend?

Katayama et al (2004). used the RHT model to simulate the impact of a B747 into an RC wall. The quantitative accuracy of the simulation was not discussed in detail and the RHT model is heavily reliant upon empirical data (although it does accurately predict the results of the above experiment). In any case, the paper concludes that a B747 impacting at 300 km/h could cause “outstanding scabbing” and a possible “fracture” of a 2m-thick-RC wall, as well as complete penetration of thinner RC walls.

@alexandervorn you are right in the case that only the engines should penetrate when kamikazes struck boats the only thing that penetrated was the engines but in the case of 9/11 even the lightweight hollow fuselage and wings penetrated thick steel which im my opinion after seeing the 1945 b-25 crash and the 2005 iran c130 crash where both planes did not enter the buildings

@poznanski666 The ‘more important thing to be discussing’, in my opinion, is the weight and density of the b747’s engines in comparison to the F4’s engines. As far RC impact modelling is concerned, airliner fuselages are, typically, modelled as ‘soft’, deformable missiles (much for the reason you discussed). Engines, on the hand, are—due to their mass and density—modelled as ‘hard’ missiles. They’re the most important thing to account for in penetration modelling. Thanks for the reply! :)

@poznanski666 It had windows though.

[poznanski666]

@Mixonpl but you do know steel in denser than concrete making it stronger according to newtons laws of depth impact

[poznanski666]

@alexandervorn i think the more important thing to be discussing is impact spread the 747 or any airliners nose is significantly larger in space but not in mass therefore it dosent concentrate or its energy to a small point like an armor piercing round would.

@fafaijoppii a jet just turned to dust. are you seriously asking if it will blend? wow ...

[TheOriginalEntz]

@bravoaya actually the pentago WAS reinforced like that. in fact just months leading up to the attack they re-inforced only the wall where the building got hit. They knew it was going t happen.

[bravoaya]

@RickAstley56 There is quite much difference between an airliner and a fighter. Also, Pentagon is not build in reinforced concrete like a nuclear power station. It is not necessary to have 1,5 meter thick walls.

[RickAstley56]

Amazing. Shows no plane hit the pentagon as the plane should have been obliterated into dust and how they were able to identify most of the over 100 killed I don't think so
