@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered.
Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb.
Booster is purging all 33 engine shrouds in flight to prevent this.
@Erdayastronaut@SpaceX@Caspar_Stanley@IzanRamos2002使发动机能够在没有护罩的情况下吸收热量，从各方面考虑，可能节省10吨以上。
护罩也有风险，因为燃油泄漏可能被护罩控制，形成MOX炸弹。
助推器正在清除飞行中的所有33个发动机护罩，以防止出现这种情况。
