In this hands-on workshop using MathWorks cloud tools, you will use a digital twin of a quadcopter to collect simulation data, analyze collision avoidance controls, and test scenarios to ensure the drone can accomplish its critical mission. Digital twin has become one of the most promising emerging technologies. The digital representations used to simulate physical systems are known as digital twins, and each physical entity has its own digital representation. Using models of machines and systems, you can run simulations before actual devices are built and deployed.

This is an exciting time to watch as simulation and science redefine planetary exploration.Simulation is becoming increasingly important in today’s world. “Aptly named, Ingenuity is a technology demonstration that aims to be the first powered flight on another world and, if successful, could further expand our horizons and broaden the scope of what is possible with Mars exploration.” Similarly, we want to learn about the potential Ingenuity has for the future of science research,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters via a press release. “When NASA’s Sojourner rover landed on Mars in 1997, it proved that roving the Red Planet was possible and completely redefined our approach to how we explore Mars.

As NASA says: These accomplishments have already pushed the boundaries of flight. They have already demonstrated that it is theoretically possible to build an ultra-lightweight craft that could generate enough lift in Mars’ thin atmosphere to take off from the ground, and operate and survive autonomously in the challenging Martian environment. If successful, it will have been the result of more than six years of work by engineers on the Ingenuity team. Ingenuity is what is known as a technology demonstration – a project that seeks to test a new capability for the first time, with limited scope, according to NASA. Finally, a quadcopter would have difficulty being stowed and then unfolded from the belly of the Perseverance rover. Extra rotor supports and multiple motors add weight. Additionally, a quadcopter would be slightly heavier for the amount of thrust produced. A quadcopter, with its four independent rotors, does not have this advantage. This phenomena allows the lower rotor to provide more lift. Pressure zones under the lower rotor are larger because the upper rotor has already compressed the thin Martian atmosphere. The image above depicts zones of high pressure under the rotors. Simulation of the advanced flight control systems is the key to safe flights on Mars, but this requires accurate aerodynamic data.įlight on Mars may be theoretically possible, but will there be enough control to let it succeed?Īn Ansys simulation showing zones of high pressure under the Ingenuity helicopter rotors. To avoid crashing, continuous corrections are required to rotor pitch, roll and angle of attack on a millisecond-by-millisecond basis.

Once Ingenuity leaves the ground, maintaining directional control in such a thin atmosphere is the big concern.

Average temperature of -60 C (-76 F), with nights as cold as -90 C (-130 F) at Jezero Crater.

The Martian flight environment is vastly different from Earth’s: The Ingenuity helicopter will rely on a light design, large coaxial rotors and the lower Martian gravity to fly in such extreme conditions. On the surface of Mars, the atmospheric density is equivalent to Earth at 100,000 feet. The air at that stratospheric level is so thin that North’s helicopter rotors could no longer lift him higher. The world altitude record for helicopter flight on Earth is held by Frenchman Frédéric North 1 at 42,500 feet. The main challenge to Mars flight is the very thin atmosphere. Accurate recreation of another planet’s gravity and atmosphere on Earth is nearly impossible, so the key to a successful maiden flight will be simulations that are truly out of this world. Simulation and wind tunnels are critical to flight tests because they can replicate what an aircraft will experience. It is difficult to anticipate the potential challenges of flying on Mars.
