Ingenuity Helicopter, Design, Challenges (mise à jour 2024)

The Ingenuity Mars Helicopter is a technology demonstration project to show that controlled flight is possible in the thin Martian atmosphere.

The helicopter is designed to take off from the ground and fly short flights, up to about 5 minutes long. It will then land back on the ground using a set of wheels attached to its body.

The Ingenuity team is made up of engineers and scientists from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. JPL is responsible for designing, building, and testing the helicopter.

The Ingenuity team also includes experts in Mars’ atmosphere and terrain from NASA’s Ames Research Center in Moffett Field, California; Langley Research Center in Hampton, Virginia; and Glenn Research Center in Cleveland, Ohio.

The helicopter is scheduled to launch to Mars aboard NASA’s Perseverance rover in July 2020. The rover will carry the helicopter to Mars’ Jezero Crater, where it will set the helicopter down on the Martian surface.

Once on Mars, the helicopter will be able to fly several short flights, testing its capabilities in the Martian atmosphere. It is hoped that the demonstration will pave the way for future Mars missions that could use helicopters to explore the planet’s surface.

The Ingenuity team has been working on the project for several years, and they have had to overcome several challenges to make the helicopter a reality.

In this article, we will take a look at the engineering challenges that had to be overcome to make the Ingenuity Mars Helicopter a reality.

The Difficulties of Flight in the Atmosphere of Mars

The first challenge that the Ingenuity team had to overcome was designing a machine that could fly in the extremely thin atmosphere of Mars. The atmospheric pressure on Mars is only about one percent of that on Earth. This means that there is very little air for the helicopter’s blades to push against as they spin.

The Ingenuity team had to design a very light helicopter to overcome this. The helicopter’s body is made mostly of carbon fiber, which is lighter than aluminum but just as strong.

The blades are also made of carbon fiber and much thinner than the blades on a typical Earth helicopter.

The Ingenuity team also had to design a very powerful motor for the helicopter. The motor has to spin the blades at about 2,400 rpm to generate enough lift to keep the helicopter airborne.

Another challenge that had to be overcome was the fact that Mars has only 38% of the gravity that we have on Earth. This means that the Ingenuity team had to design a landing system that could safely land the helicopter on the Martian surface. The team decided to use a set of wheels attached to the body of the helicopter.

About Ingenuity

The first stages of Ingenuity’s design began in 2014. It was designed to serve as a “scout” unit for the Mars rover, assisting in the identification of safe driving routes. Prototypes of the Ingenuity helicopter have been created and tested on simulated Mars terrain over the years.

The project was awarded $23 million in federal funding in 2018, just in time for the chopper to be deployed for NASA’s Mars 2020 mission.

Following a series of flight tests, it was agreed that the helicopter would be mounted on the rover’s underbelly. The helicopter would not be formally named “Ingenuity” – or “Ginny” for short – until April 2020.

The Ingenuity was primarily intended to be a technological showcase. NASA scientists can then use the data and performance of the Ingenuity to develop more advanced versions of the helicopter that can serve the actual objective of being a scout drone.

The Ingenuity completed its inaugural flight on April 19, 2021. The brief flight consisted of merely taking off, rising to a height of ten feet, hovering for over 40 seconds, and landing. The flight’s footage was then obtained three hours later.

Design Elements of Ingenuity

The design elements of the Ingenuity are vital to its success as a flying machine on Mars. The following are some of the most important design elements:

Lift

The lift rotors are the blades that spin to provide lift for the helicopter. The blades are made of carbon fiber and are just over four feet in length.

Poids

The Ingenuity weighs just over four pounds, making it one of the lightest helicopters ever built.

Contrôle

The Ingenuity is controlled by a computer that is programmed with the flight path. The computer controls the blades and the motor to keep the helicopter on course.

Power

The Ingenuity is powered by batteries that are charged by solar panels. The power system is designed to be as lightweight and efficient as possible.

Durabilité

The Ingenuity is designed to be durable enough to withstand the Martian environment. The body of the helicopter is made of carbon fiber, which is strong but lightweight.

Advancement of the Ingenuity Drone

The team at NASA may now use the acquired data for future iterations after Ingenuity’s tech demonstration was a huge success. The goal is to develop a drone that can carry a payload and function at larger weights.

The drone’s ultimate goal is to gather soil, water, and brine samples from Mars, which will subsequently be sent back to Earth for analysis.

Conclusion

The Ingenuity helicopter is a remarkable achievement. It has overcome many challenges to become the first machine to fly on Mars.

The data from Ingenuity’s flights will be used to design more advanced versions of the helicopter that can be used for actual scouting missions. It is hoped that the Ingenuity will pave the way for a new era of exploration on Mars.
