Russian startup Flyter has taken the next important step in testing the design of its 2-seater PAC 720-200. 

The Flyter PAC 720-200 is capable of carrying 440 lbs with a max range of 560 miles.

Flyter has been around since February 2018. Since then, it unveiled its concept for the PAC 720-200, a two-seater VTOL aircraft that flies like a small plane but can take off like a helicopter. Flyter’s goal is to make an aircraft that can both use airports as well as access more remote locations.

The Flyter 720-200 features a total of eight downward-facing lift propellors. Flyter states that although the it would have liked to use only four props, efficiency and thrust requirements led to the four-prop design.

In the latest test, Flyter successfully proves many of the predicted thrust and efficiency calculations. The design itself is unique in that propellors sit under the wing rather than on top of it, and the test proved the functionality of this concept. While many eVTOL prototypes (such as the Boeing PAV) use only upward facing propellors and others use a combination of upward and downward facing propellors, Flyter is one of the only companies to use solely downward facing propellors.

Watch the company’s full description of the flight test below:

Flyter is also one of the only eVTOL developers in Russia, and is proceeding with testing on schedule. The company begun taking investors in April of this year. Rather than targeting an urban air taxi market, Flyter’s strategy is to provide a vehicle that can access remote locations of Russia. The company will make both a passenger and autonomous cargo version of the PAC 720-200, and intends to use hybrid power for maximum range.

Why it’s important: Since Flyter is one of the only eVTOL developers in Russia, it has a good chance of being first to capture VTOL flight demand there. Through its latest round successful of testing, Flyter sets a precedent for future progress, securing itself as a technology leader in Russia. Flyter’s next steps will involve continuous testing and eventual prototyping and certification.

Innovation is soaring to new heights in aerial mobility, and recent advances in artificial intelligence (AI) are challenging the ways traditional methods of flight path monitoring. While there is the potential to significantly enhance safety and efficiency in our increasingly crowded skies, there are also challenges related to how cutting-edge AI technologies can be safely and responsibly applied to new aircraft.

The Challenge of Aerial Mobility

Aerial mobility continues to make inroads on the path to widespread certification and utilization of aircraft to decongest urban areas and more efficiently transport passengers the last 50nm of their trips. With the rapid growth of drones, air taxis, and autonomous aircraft, cities around the world are embracing the potential for faster, cleaner, and more efficient transportation. However, this comes with its own set of challenges, particularly in managing and coordinating the movement of numerous airborne vehicles in urban environments.

AI-Powered Predictive Flight Path Monitoring

AI-driven predictive flight path monitoring has a potential to be a game-changer in this space, but with serious complications if implementation isn’t nearly flawless. AI algorithms, empowered by deep learning and real-time data analysis, enable aerial mobility systems to anticipate and adapt to changing conditions. A potential rosy future could include:

1. Collision Avoidance: AI algorithms can predict potential conflicts between aerial vehicles and suggest alternative routes to avoid collisions. This proactive approach significantly reduces the risk of accidents, making urban air travel safer for everyone.
2. Weather Forecasting: AI can process vast amounts of weather data in real-time, allowing aircraft to adjust their routes to avoid turbulence, storms, or adverse conditions. This not only enhances safety but also ensures smoother and more comfortable rides for passengers.
3. Traffic Management: AI-powered traffic management systems can dynamically allocate airspace and landing zones, optimizing routes to minimize congestion and delays. This promotes efficient use of airspace, reducing travel times and environmental impact.
4. Predictive Maintenance: AI can predict maintenance needs for aerial vehicles by analyzing sensor data. This preemptive approach ensures that aircraft are in optimal condition, reducing the risk of in-flight mechanical failures.

While the above list of advances sounds incredibly convenient, it also reflects what many sight as an idyllic view of AI’s implementation in aerial mobility. There are numerous challenges to face, including sporadic, erratic flight paths from other aircraft, regulatory integration and certification, as well as ethical and privacy concerns, especially for those not wanting the data from their flights to be shared for privacy reasons. Finally, the methods by which these algorithms are trained must be ironclad, and evasive actions cannot also be prescribed in situations where immediate intervention is necessary.

As many OEMs adopt hybridized approaches to their powertrains, leveraging the best of both internal combustion and battery technology, a similar approach is likely warranted for the most successful of the aerial mobility aircraft: provisioned for future growth with capabilities that can eventually be fully autonomous, but with the option for remote or in-aircraft piloting to occur to assuage passenger concerns and to meet current regulatory requirements.

Why it’s important: As AI continues to evolve, the future of aerial mobility may evolve to leverage this technology as well. AI-driven predictive flight path monitoring may enhance safety but also paves the way for increased automation and autonomy in air travel, if implemented gradually and successful. The runway to AI integration into aviation is a long one, but slow incremental steps will yield benefit.

In a letter to investors for public release, Vertical Aerospace has shared an update on its flight test program following an incident last month involving one of its VX4 flight test prototype aircraft. According to the release, Vertical does not expect any significant impact to its certification timeline.

The release stated the VX4 flight test prototype has concluded its remote thrustborne flight test campaign as of July 2023, as the first full-scale VX4 prototype reached its target speed of 40kts (70 kmph), demonstrating exceptional overall stability and control.

Performance targets were generally exceeded by 10-30% during hover and low speed flights. The prototype performed especially well in sustained hover, typically the most challenging regime for a VTOL aircraft, where it maintained level flight for longer than anticipated. The aim of these thrustborne flight tests was to verify acceptable stability, battery efficiency and control characteristics, aerodynamics, structural loads, performance and vibration throughout this speed range – all of which were achieved.

During one of these test flights, an unexpected fault occurred causing the aircraft to enter a stable descent, before being damaged on impact with the ground. Vertical completed a swift and thorough investigation and submitted a report to the Air Accidents Investigation Branch (AAIB). Vertical’s investigation identified the root cause to be a fault with a propeller. This early generation propeller had already been redesigned prior to the incident, with the issue fully resolved ahead of the next phase of testing. Further recommendations by the investigation are being implemented by Vertical.

Stephen Fitzpatrick, Vertical Founder and CEO, commented: “We are pleased with our flight test progress to date and the data, insights and invaluable learnings we have collected. While a fault of any sort is disappointing, it is not wholly unexpected at this stage of testing a novel aircraft. I am pleased that as a result of our expert team we have isolated the cause of the fault and been able to provide the AAIB with our report within 14 days of the incident. Our planned second upgraded prototype, which will include most of our top tier partners’ technology, will have us in the air early next year and we remain on track for our certification timelines”

Why it matters: Despite the setback of a flight test incident, Vertical remains on track for its certification timeline. The company stated it is also developing a second, more advanced flight test prototype of the VX4 model which will be ready to fly in early 2024. Expect more updates as Vertical progresses toward entry to service of its eVTOL aircraft.
