Por que as naves não queimam na reentrada no universo de Star Wars?

7

No universo de Star Wars, vimos navios entrarem e saírem das atmosferas sem problemas. No entanto, na vida real, os navios que reentrem as atmosferas tendem a reaquecer. Nós só vemos uma vez que um navio queima na reentrada, e isso é em Vingança dos Sith, onde a nave capital está desabando para Coruscant. Existe alguma explicação sobre por que os navios não geram calor quando reentram na atmosfera de um planeta?

Rey pratica em um simulador em Star Wars: Antes do Despertar . Como você pode ver, um dos elementos-chave para uma entrada atmosférica segura e bem-sucedida é o uso de motores de repulsão . Teoricamente, um navio que chegasse em um ângulo alto o suficiente não experimentaria praticamente nenhum aquecimento da atmosfera, presumindo que ele tivesse algum tempo de se desacelerar antes de ser enterrado no solo.

At first, she’d been truly horrible at it, quite literally crashing a few seconds after takeoff every time. With nothing else to do, and with a perverse sense of determination that she would not allow herself to be beaten by a machine that she herself had put together with her own hands, she learned. She learned so much that there was little the program could throw her way that would challenge her now. She’d gotten to the point where she would, quite deliberately, do everything she could think of to make things hard on herself, just to see if she could get out of it. Full-throttle atmospheric reentry with repulsor-engine failure? No sweat.

Sabemos da novela júnior de Star Wars: A Vingança dos Sith que embarcações maiores têm físico escudos térmicos.

Through the smoking viewport, Anakin caught glimpses of the towering buildings of Coruscant streaking past below them. Too close. We’re too low, too soon. R2-D2 beeped madly, and Anakin gestured at one of the controls. “Keep us level,” he told the droid, and went back to work to slow them down.
“Steady,” Obi-Wan said. “Five thousand.”
“Hang on,” Anakin said. “This may get a little rough. We lost our heat shields.” “Landing strip’s straight ahead,” Obi-Wan said a moment later.

There was little she could do, except put the life pod’s reentry heat shield between them and the blast. The TIE fighter pursuing them was slower to react. Superheated particles from the explosion ripped through the vessel’s hexagonal wings, causing the starfighter to tear violently apart. A shock wave comprising not air but plasma and matter expanding outward from the blast zone slammed into their life pod.
