Congested streets and pollution are already a reality in many European cities, as indicated by the TomTom Traffic Index 2020 and the Air quality in Europe 2020 report by the European Environment Agency. With the population of cities in the European Union set to grow to more than 340 million citizens by 2030, there is a risk of increased pollution and congestion.
In this context, local authorities are looking at greener, more integrated, and sustainable mobility solutions.
Adding a new dimension to urban transportation will allow air transport of goods and people and may also help to make a leap towards smarter and more sustainable cities.
UAM is expected to bring environmental benefits as well as advantages for citizens and businesses - notably for commercial or emergency/medical arenas.
A demand modeling performed using a five-step process, including: trip generation, scoping, trip distribution, mode choice, and constraints has demonstrated that UASystems eZELOS propulsion system is the right answer to the above emerging markets.
Product Overview
eZELOS is a ground-breaking hybrid-electric flight platform. It is a faster, cleaner, safer, smarter way of moving people or goods than other existing or envisioned VTOL options.
Innovations as paired with proven, simple, and robust technology create the necessary premises for rapid certification and consequently a fast introduction in operation.
Its ability to handle a high payload with minimal power requirements is evidence of the propulsion solution efficiency. Under the same payload conditions, eZELOS is smaller and lighter than single rotor or multi-rotor configurations. It presents the highest level of compactness, and this significantly reduces the space required for vehicle storage, enabling operation virtually from anywhere.
The performance in flight, even in strong winds, is practically unbeaten.
The coaxial configuration helicopter is so special because it embodies a principle of the reactive moment compensation fundamentally different from that of the single rotor configuration.
The coaxial rotor eZELOS has its rotors' reactive moments compensating each other directly in their axis of rotation. This removes the need for any additional control forces. The rotors' reactive moments are compensated automatically throughout the flight, thus requiring no interference from the pilot.
Given that the coaxial-rotor helicopter does not have to use power for compensating the reactive moment, coaxial helicopters appear to be 16-22% more efficient than single-rotor aircraft. The above power considerations provide the coaxial configuration with substantial advantages in hover ceiling (by 500-1,000m) and vertical rate of climb (by 4-5 m/sec).
The coaxial configuration results in reducing the aircraft size by 35-40% as compared with the single rotor case. This is mainly due to the reduction in the rotor's diameter thanks to greater natural finesse in hover and no power loss to tail rotor (eZELOS has no tail rotor). The aircraft size is further reduced because there is no need for a long tail boom on which to mount the tail rotor - outside the main rotor's blade-swept area.
The contra-rotation of coaxial rotors leads to significant reduction in power, since the airflow from the rotors exhibits much less lossy rotation (swirl). Flight testing as well as other experimental data shows coaxial rotors to be 6-10% more efficient as compared to single rotor helicopter equivalents.
The coaxial-rotor helicopter's reduction in size and different weight distribution along the airframe results in considerable reduction in longitudinal and directional moments of inertia. This fundamentally improves controllability of the aircraft.
Aerodynamic symmetry is the most important feature of the coaxial helicopter. It enhances its controllability and stability substantially, partly because the aircraft experiences little torque disturbance forces resulting from lateral airflow (including wind). Thanks to having no tail rotor, the eZELOS is not subject to the constant effect of an alternate side force.
This good controllability is essential in a high-density obstacle environment.
eZELOS has independent control and it is easy to master by any pilot irrespective of his flying skills. Flight safety is therefore enhanced and flying in extreme conditions gets easier, which is especially true as far as low altitude flying, small landing pads, broken terrain, high barometric altitude, including concerns regarding systems' failure.
For UASystems the safety characteristic is defined as paramount and the eZELOS design satisfies this request at the full extent of the operational envelope.
Key Contributors & Certification Strategy
The Type Certificate (TC) is the most discussed certification issue amongst AAM players as it relates to aircraft systems as a whole and, therefore, the interaction between all novel technologies. It covers the aircraft’s design, including components and the safety bar is identical to the high standards of commercial fixed-wing airplanes. The new configurations of UAM aircraft, other than eZELOS, are usually a hybrid between traditional rotorcraft and fixed-wing aircraft, and there is no clear path for certification on the regulator’s side, for the time being.
The eZELOS design fits perfectly into the rotorcraft category simplifying considerably the certification process. The CS-27/Part 27 regulations are well defined and often used.
Action: Jointly develop and explore potential certification possibilities before applying for the official type certification process
UASystems is well prepared to overcome the complex task of securing all the necessary certifications in time for eZELOS planned entry into service (EIS) date.
The developed mitigation strategies address the four major challenges around eZELOS certification.
[1] Uncertainty Collaboration with the regulator is key;
[2] Overseeing organizational approval: Focus on DOA, POA and TC;
[3] Lack of business maturity: Organization robust and readiness;
[4] Gaps in expertise: Experience and talent are critical enablers.
Senior engineering talent with certification expertise and practice are essentially required.
Pricing Target
The projected list price for eZELOS is US$850,000.
Action: Leverage the benefits of obtaining Design Organization Approval (DOA) and Production Organization Approval (POA) to speed up internal processes due to higher regulator confidence.
Action: Balance formalized processes and agility of the organization to pass the certification audits without losing momentum and speed.
With type certification therefore dependent on both aircraft design and propulsion technology, UASystems has chosen the right approach to certification in terms of associated risk for their specific development program, by using existing and proven aircraft design and adding new hybrid-electric propulsion.
Market Analysis Industry Type
UASystems has a thorough knowledge of current and potential markets for its services. It has carefully identified the “Customers” with their requirements and distinguished them from “Consumers”. The market segmentation has been executed in a dynamic rather than a static sense and anticipates future changes in customer needs. Therefore, the eZELOS design offers the necessary flexibility to address them. With the legislative compliances being released by the top aviation bodies (FAA, NASA & EASA) & the infrastructure development taking shape in big cities, the big investments into UAM should justify the means that are being considered for it.
The International Air Transport Association (IATA) has estimated that the number of passengers traveling by aircraft could double to 8.2 billion by 2037. According to the UN, 68% of the population is expected to live in urban areas by 2050. The growing number of vehicles in urban areas has resulted in several traffic and mobility issues, which in turn are driving the demand for alternative modes of transportation. The cost of an eVTOL ride is less when compared to helicopters. Uber Elevate estimated that fully electric air taxis would have near-term operating costs of around USD 700 per hour, at least 35% less than a comparably utilized single-engine helicopter.
The electric Vertical Take-Off and Landing (eVTOL) aircraft will replace the Lightweight Helicopter (LH) in coast guard surveillance, police department, logistics, tourism, health care, private VIP flights, flying club ownerships, private ownership, and “so on”.
For civilian utilization the cost/mile is extremely important, in driving the market towards Morgan Stanley's predicted (1.3 trillion dollars) industry by 2040. Driven by economics, the eZELOS design guarantees 60% reduction in operational costs, cleaner, quieter, and cheaper transport than similar LH offerings.
The market will be stimulated based on the technology trends and the current state could multiply more than 100 times. This constitutes an unprecedented 35 billion dollars in the next 10 years based on public demands for short range travel, logistics and civil emergency requirements.
eZELOS with its low cost per mile ratio and an accessible list price is ready to join the next boom cycle in the vertical transportation industry that will change aviation for the better.
Market Segmentation
The urban air mobility market is fragmented, with very few companies accounting for a significant market share in 2022. Volocopter GmbH, EHang Ltd, Joby Aero, Inc., and Jaunt Air Mobility Corporation are some prominent players in the UAM market. The market is still in its development phase, with many players, through collaborations and partnerships, trying to deliver the first UAM units to their customers in the coming years.
Currently, UASystems has MOUs for up to 700 eZELOS from Asia Pacific aircraft operators/aerial mobility service providers and governmental entities. As the company is completing the realization of the first eZELOS prototype, flight testing is expected to begin shortly, soon allowing it to enhance its market visibility.
UASytems is ready to seize the opportunity of vertical mobility and to establish strong partnerships with public and private entities for success. The eZELOS promise is to democratize vertical mobility with its long range, low cost of operation, efficiency and before anything else, the highest available standards of safety.
Hybrid propulsion VTOL aircraft shall also have a positive impact on emergency, safety, and rescue operations.
With a pilot on-board, eZELOS is ready to become commercially successful and socially accepted, establishing public approval within the framework of rules and regulations, being accessible to all, at an acceptable price and environmental impact.
Concept of Operations
Passenger taxis will for some time remain a hub-to-hub travel option that depends on other modes of transportation, rather than an end-to-end solution.
The success of eZELOS as a commercial vehicle will derive largely from its ability to fly new routes from city centers to city centers and beyond, between major metropolitan areas offering low-emission, low-noise, and cost-efficient movement.
This will save the business traveler time from the central business district to the airport and/or surrounding areas. For example, because the eZELOS can fly 130 knots, it can make the trip from Dubai to Abu-Dhabi in the same time or less than a jet that may fly at 440 knots maximum air speed. The jet must spend considerably more time taxiing, waiting to take off, climbing to altitude and to its route, and maneuvering for position to land.
Looking at eVTOL aircraft, the market for inspection types will grow to $34 billion by 2035, complemented by the market for goods-and-delivery at $4 billion. Unmanned inspection aircraft are in use today, and automated goods vehicles are already being tested around the world. The market for supporting services around inspection, goods, and passenger drones will reach another $4 billion by 2035.
A strong emphasis is placed upon the value of intermodal in the passenger transportation system. It is most visible in containerized freight systems, in which a Lift On/Lift Off container ship docks in a harbor with direct crane loading access to both a railroad spur and a tractor truck staging area. At this intermodal point, it becomes possible to transfer freight between any of the three vehicles.
Intermodal passenger transportation should work essentially in the same manner. From eVTOL, passengers may transfer inter-modally to automobiles, buses, rail, subway, ferry, or to a jet aircraft.
Competition:
eVTOL Market Leaders as compared with the eZELOS
#1. On May 9th, 2022, FAA ruling stated that winged eVTOLs cannot be certificated under 14 CFR Part 23.
#2. None of the current AirTaxi Market Leaders have never manufactured any aircraft with completed certifications and are in production today.
Current eVTOLs come in all shapes and sizes, and all are powered by electric motors and batteries and capable of taking off and landing like a helicopter.
Their advantage is fuel savings and no emissions, their disadvantage is lack of range and certification issues.
For the moment, eVTOLs should be best suited for short endurance missions and in areas where batteries recharging is convenient. However, endurance is a vital concern, as any detour from the Flight Plan will be a safety issue.
This is not the case for the eZELOS that aims to be the safest AAM aircraft for all.
The aim of the eZELOS is to become the main option for its replacement on the market in the years to come.
Sourcing
Our design team is fully aware of all the component dependencies they are using, and they think of the consequences of using dependencies. These dependencies are logged into an inventory system.
The purpose is to avoid the use of parts or services that can be subject to obsolescence, temporary unavailability due to supply chain disruptions, sanctions, and/or third-party restrictions.
This enhances the reliability of the eZELOS production and operation.
Technology
The AAM is driven in part by advancements in batteries, distributed electric propulsion, and autonomy technologies that lead to the development of a new class of eVTOL aircraft.
There is a fundamental trade-off between battery size and mission length. On one hand, bigger batteries have more energy, which can translate into longer missions.
However, with the increase in battery size comes additional aircraft weight, which can translate to increased acquisition cost.
Based on current battery technology, eVTOL aircraft will likely need to be partially or fully recharged after each mission. Given current battery-charging technologies, the time to perform this charging is likely to deter high aircraft utilization, particularly during peak demand periods. The amount of electricity required to power an electric fleet of aircraft is not trivial and will likely have significant impacts on the electric grid, which may not be able to be supported by the current electric grid.
eZELOS tackles all these limitations with the twin hybrid propulsion system making use of the batteries only for two phases of the flight and as back-up for emergency situations. In this way, eZELOS is ready for a much higher pace of operations, with a flight range that goes beyond the intracity or urban travel extending since day one to regional and intercity missions.
The selected propulsion solution is composed of six electric motors, two super-efficient ICE (internal combustion engines), batteries and a proprietary complex control system.
A typical Air Taxi mission comprises of five main phases of flight: takeoff, climb, cruise, descent, and disembarkation and the eZELOS is prepared to execute it with the minimum noise and pollution impact possible.
Taking off and landing in “electric” mode, arriving to the cruising altitude and flying toward the destination in “hybrid” mode, self-generating the energy for the electrical motors and concluding at destination with a smooth and almost silent “electric landing" and taxi depicts eZELOS approach to maximum fly efficiency.
Manufacturing Facilities
eZELOS final assembly is to take place in Selzach, Switzerland, and in locations/facilities with strategic manufacturing and distribution partners.
UASystems promotes eZELOS to companies that prioritize customer experience and are in the best position to capture value and build sustainable businesses.
This is because 35 percent to 50 percent of value from AAM comes from segments that involve direct customer interactions, including mobility platforms and infrastructure.
As an OEM we are creating the use cases and CONOPS about how they will operate the eZELOS aircraft and the customer-experience considerations have always emerged as being vitally important.
To date we have been focusing on design, manufacturing, and certification issues. But this is done in parallel with building the closest possible relationship with partners as well as with customers, to be in the best position to capture value, drive retention, and build sustainable businesses in the long term.
As the AAM industry gains traction, we will be vigorously evaluating its competitive advantages to determine where it should play on the AAM value chain. To remain a successful player, we need to identify future control points and to develop a clear understanding of how the value chain could affect and shift our strategy.
eZELOS Marketing Strategy
The eZELOS is planned for airTaxi, airCargo, and/or airAmbulance applications. Innovations set us apart from the competition. eZELOS means "Electric Drive" now, "Zero Emission" next.
With our Twin-Hybrid Propulsion System, we have already reduced CO2 by 50% and operation costs by 60%, as compared to light helicopters.
In building up the strategy, we will pay full attention to variables that can impact the commercial success for the eZELOS, including:
