An officially maintained Realistic Engine And Fuel Tank And Heat Shield Mod

I am a loyal player of planetary systems like the Real Solar System. But the engine and fuel tank and heat shield of the Vanilla game obviously didn't make me happy playing with this system, so I looked for Mod that could improve this.
But in fact, I find it difficult to find Mods that can be maintained in a timely manner, as ethey always lag behind the game to the point of being plagued by bugs. So I hope the official can develop a Realistic Engine And Fuel Tank And Heat ShieldMod!
