巴西已自筹资金研制称为VLS(Veiculo Lancador de Satelites)4级式固体运载火箭。该火箭具有发射115公斤卫星到750公里高度圆轨道、160公斤卫星到650公里圆轨道的能力。巴西的研究机构INPE(Instituto de Pesquisas Espacias),自1980年起开始实施“MECB计划”,它包括将使用VLS火箭发射卫星的独自的空间开发计划。 4级式VLS固体火箭的规格如下: 第一级——4枚直径1米、长6米的固体火箭捆绑在一起。喷管是固定的,带有飞行控制用的气体喷射装置。
Brazil has raised funds to develop a 4-stage solid-vehicle rocket called VLS (Veiculo Lancador de Satelites). The rocket has the capability to launch 115 kilograms of satellites to 750 kilometers of orbital altitude, 160 kilograms of satellites to 650 kilometers of orbital orbit. INPE (Instituto de Pesquisas Espacias), a research institute in Brazil, has been implementing the “MECB Program” since 1980 and includes its own space development plan to launch satellites using VLS rocket. The specifications for the 4-stage VLS solid rocket are as follows: 1st stage - 4 solid rockets 1 meter in diameter and 6 meters in length are bundled together. The nozzle is stationary with a gas jet for flight control.
