This work analyzes aerodynamic forces in the Martian environment with the aim of evaluating the feasibility of flight on Mars. After a detailed characterization of the Martian atmosphere - considering composition, pressure, temperature, density, and viscosity - the study highlights how the low atmospheric density leads to low Reynolds numbers and thus predominantly laminar flow conditions. Two airfoil profiles, NACA 2412 and NACA 4412, are examined to compare their performance in terms of lift and drag. The results show that large wingspans are required to generate sufficient lift, with the NACA 4412 profile proving more efficient due to its higher camber. A comparison with Earth’s atmosphere reveals significant differences: on Earth, higher air density allows for more compact wings and greater aerodynamic efficiency. In conclusion, flight on Mars is feasible but requires specific and optimized design solutions.
Questo elaborato analizza le forze aerodinamiche in ambiente marziano con l’obiettivo di valutare la fattibilità del volo su Marte. Dopo una caratterizzazione dettagliata dell’atmosfera marziana - in termini di composizione, pressione, temperatura, densità e viscosità - il lavoro evidenzia come la bassa densità comporti numeri di Reynolds ridotti e quindi un regime prevalentemente laminare. Vengono studiati due profili alari, NACA 2412 e NACA 4412, per confrontarne prestazioni in termini di portanza e resistenza. I risultati mostrano che, per generare sufficiente lift, sono necessarie ali di grande apertura, con il profilo NACA 4412 più efficiente grazie alla maggiore curvatura. Il confronto con l’atmosfera terrestre mette in luce differenze significative: sulla Terra, la maggiore densità consente ali più compatte e un’efficienza aerodinamica superiore. In conclusione, il volo su Marte è possibile ma richiede soluzioni progettuali specifiche e ottimizzate.

Abstract
This work analyzes aerodynamic forces in the Martian environment with the aim of evaluating the feasibility of flight on Mars. After a detailed characterization of the Martian atmosphere - considering composition, pressure, temperature, density, and viscosity - the study highlights how the low atmospheric density leads to low Reynolds numbers and thus predominantly laminar flow conditions. Two airfoil profiles, NACA 2412 and NACA 4412, are examined to compare their performance in terms of lift and drag. The results show that large wingspans are required to generate sufficient lift, with the NACA 4412 profile proving more efficient due to its higher camber. A comparison with Earth’s atmosphere reveals significant differences: on Earth, higher air density allows for more compact wings and greater aerodynamic efficiency. In conclusion, flight on Mars is feasible but requires specific and optimized design solutions.| File | Dimensione | Formato | |
