Estudo de caso sobre o efeito da radiação cósmica em sistemas embarcados em aeronaves

Abstract: Nêutrons de alta energia, gerados a partir da interação da radiação cósmica com átomos da atmosfera, podem provocar efeitos indesejáveis nos dispositivos aviônicos. Estes efeitos são denominados como Single Event Effects (SEE) e podem ocorrer principalmente em computadores de bordo de aeronaves provenientes da mudança do estado lógico de células de memória ou em interrupções funcionais, podendo comprometer a segurança de voo. Os efeitos de SEE devem ser previamente avaliados e inseridos no processo de análise … Show more

“…The competitiveness drivers as shown in Figure 1, applied to the agroindustrial production chain according to the methodology proposed by César and Batalha [15] were: macroeconomic factors, technology, programs and sector policies, market structure, governance structure, productive resources, management, and infrastructure [16]. These eight competitiveness drivers and their application to the biodiesel production chain were studied to acquire the necessary knowledge to study the competitiveness of the di-amyl ether biofuel, this occurs because biofuel production presents inputs from ethanol, which in turn has a complex agro-industrial chain.…”

“…Os resultados obtidos mostraram que os alunos do curso, na instrução do voo do T-27 Tucano, não sofrem efeitos imediatos, nem de médio prazo, da absorção de dose mínima de radiação cósmica, pois supõese que a missão adotada para efeito de cálculo foi representativa do contexto. Efeitos em longo prazoos estocásticospodem ser decorrentes de outros fatores, por hora desconhecidos no âmbito científico (GONÇALVES, 2012;PRADO et al, 2015).…”

“…All of these particles impact sensitive regions of integrated circuits, causing the rapid collection of the released electrical charges and consequently the SEEs. Single event effects can occur mainly in aircraft onboard computers, resulting from the change in the logical state of memory cells or in functional interruptions, which can compromise flight safety (Prado et al 2015).…”
