Como Explorar Hohmann Transfer 3D Explorer - Passo a Passo


O Hohmann Transfer 3D Explorer comeca assim que a pagina carrega: arraste para orbitar a visualizacao, role ou belisque para ampliar, e pressione Play transfer para disparar as duas queimas. Tudo roda no seu proprio dispositivo - sem instalacao, sem conta.


Abrir a cena

Carregue a pagina e o preset LEO to GEO aparece por padrao, com a nave em repouso no anel orbital interno. O motor 3D e baixado uma vez e fica em cache. Se o WebGL nao estiver disponivel, aparece um aviso simples em vez de uma tela quebrada, e o painel de dados continua funcionando normalmente.


Escolher um preset

Pressione LEO to GEO para a transferencia em escala de satelite (r1=6,678 km, r2=42,164 km) ou Earth to Mars para a transferencia interplanetaria (r1=1.0 AU, r2=1.524 AU). Cada preset redesenha os aneis orbitais interno e externo, a elipse de transferencia e o painel de dados juntos.


Disparar a transferencia

Pressione Play transfer. O botao muda para Transferring enquanto a nave percorre a elipse turquesa do marcador turquesa de partida ao marcador laranja de chegada em cerca de tres segundos de animacao - representando exatamente a metade da orbita de transferencia real. Ao chegar, o botao muda para Reset to inner orbit.


Verificar uma unica queima

Clique apenas no marcador turquesa para o delta-v da queima de partida, ou no marcador laranja para a queima de chegada. Para LEO to GEO esses valores sao 2.45 km/s e 1.47 km/s; para Earth to Mars o valor publicado cobre toda a manobra em vez de uma divisao clara por queima.


Ler o painel de dados

O painel lista o raio orbital interno r1, o raio orbital externo r2, o tempo de transferencia e o delta-v total para o preset ativo, alem de uma nota sobre como o valor do tempo de transferencia foi obtido ou calculado. Uma nota final afirma que os raios orbitais na tela sao comprimidos para facilitar a leitura, enquanto os valores de r1, r2, tempo e delta-v sao reais.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
  • Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
  • Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
  • Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
