Le missioni di esplorazione spaziale sono l'apice della tecnologia mondiale. Se l'obiettivo è l'esplorazione superficiale extraterrestre, le tecnologie di atterraggio devono proteggere accuratamente dai danni il dispositivo nella fase più critica dell'atterraggio. Tra le altre opzioni, gli atterraggi con retropropulsione rappresentano una soluzione più volte collaudata per gli atterraggi lunari e marziani. La diversa spinta richiesta per la fase finale della discesa introduce esigenze di modulazione di portata, che vengono soddisfatte con valvole di controllo del flusso a Venturi cavitante ad area variabile. Queste valvole consentono la modulazione della spinta, il cui controllo deve essere gestito con precisione da un sottosistema elettronico che può consentire diverse opzioni di comando, tra cui è stato richiesto il bus MIL-STD-1553. Un'implementazione da zero dello stack hardware, firmware e software per consentire alla valvola di agire come "Remote Terminal" è stata progettata, sviluppata, assemblata, integrata e testata sia in laboratorio che presso il cliente, con una verifica positiva delle caratteristiche richieste.

Abstract
Space exploration missions are the pinnacle of worldly technology. If extraplanetary surface exploration is to be sought, landing technologies must accurately prevent damage to the payload in the most critical landing phase. Among other strategies, retro-propulsion landings provide a multiple times proven solution for both lunar and martian landings. The thrust modulation required for terminal descent introduces throttling needs, which are met with variable area cavitating Venturi flow control valves. These valves allow for thrust modulation, whose control must be handled accurately by an electronic subsystem, which can allow for different command options, among which MIL-STD-1553 bus was requested. A from scratch implementation of the hardware, firmware and software stack to enable the valve to act as a remote terminal was designed, developed, assembled, integrated and tested both on laboratory premises and on clients premises with a successful verification of the required features.| File | Dimensione | Formato | |
