Evolutionary optimization identifies corrugated airfoil designs for low-density atmospheres

Researchers at Tokyo Metropolitan University have used evolutionary optimization and computational fluid dynamics to investigate how corrugated, insect-inspired airfoils could improve the aerodynamic performance of very small unmanned aerial vehicles in low-Reynolds-number environments. Such conditions occur in thin atmospheres, including Mars, and also affect miniature aircraft operating on Earth. The study focused on ultra-thin, membrane-like wings. These structures are attractive for planetary UAVs because they can be lightweight and compact, while their aerodynamic behavior can resemble that of insect wings. The researchers specifically examined the effect of corrugation patterns by using a computationally idealized “zero-thickness” airfoil model. Although such an airfoil cannot be built physically, it allowed the team to isolate the influence of the corrugation geometry from effects caused by the thickness and shape of a wing’s leading edge. An evolutionary algorithm generated and evaluated different airfoil geometries through aerodynamic simulations, optimizing them for different objectives. Designs targeting minimum drag showed that certain corrugations near the leading edge could produce recirculating airflow that reduced frictional drag compared with a flat sheet. Designs optimized for maximum lift displayed a different pattern: they generally contained few corrugations, had an overall convex profile, and incorporated concave features toward the trailing edge. The researchers note that insects can naturally deform their membrane-like wings, combining corrugated and cambered configurations. This flexibility could provide inspiration for future three-dimensional UAV wing designs capable of adapting to different flight conditions. The findings may contribute to the development of smaller aircraft for Earth and to lightweight aerial vehicles intended to operate in thin planetary atmospheres.

These are the only Earth creatures tough enough to survive on Mars

Mars is a pretty horrible place for any creature used to life on Earth. The average surface temperature is -63°C (-81°F) and doesn’t reach above freezing anywhere except right on the equator, during the summer. The atmospheric pressure is equivalent to Earth’s at an altitude of 35km (almost 115,000ft) – well above the cruising altitude of commercial aircraft. And this thin atmosphere is nearly all carbon dioxide, with just the merest trace of oxygen. Then there are the radiation levels, which are 400 times higher than on Earth, plus the lack of liquid water anywhere, except for occasional, very salty, trickles. Despite this, there are a few Earth organisms that have shown some capacity to withstand these conditions. The European Space Agency ran a series of experiments from 2008 to 2016 in which a variety of organisms and seeds were given simulated Martian conditions while aboard the International Space Station. Tardigrades, fungi and some bacteria survived for over a year, but only when in a dormant state, such as a spore or cyst.
