This Russian Space Flight Award Medallion was the property of NASA Langley, and I am wondering if anyone knows what it is, reads Russian, or can identify the personage on the front?Thanks in advance for your thoughts.

At first look, the engraving looks like it could be Vladimir Lenin? |

My Russian could be better, but the name translates as Academician Sergei Alexeivich, S A Chaplygin. Soviet physicist, mathematician, mechanical engineer. There is a Chaplygin equation and gas named after him. See Wikipedia.Not a name most in the space industry are familiar with. There is a lunar crater and town named after him. |

Neil, I think you have nailed it. Only thing I can't figure is the date 9/7/46, as that is after he passed. |

Thinking further, it makes sense this was NASA Langley property, as Chaplygin's equation may have been used developing their wind tunnels. In gas dynamics, Chaplygin's equation, named after Sergei Alekseevich Chaplygin (1902), is a partial differential equation useful in the study of transonic flow. | |
