Twinjet, s-duct, winglets, contra-rotating propellers: the aviation industry has developed numerous configurations over the last five decades that have enabled aircraft to fly higher, faster and longer. Now, Airbus engineers are unveiling a new configuration as part of the ZEROe programme that could enable a passenger aircraft to fly farther than ever without emissions.
The innovative approach consists of six, eight-bladed “pods” mounted beneath the aircraft wing. While the “podded” engine is not a new concept in aviation, these “pods” are not designed to be driven by any ordinary propulsion system: hydrogen fuel cells are among the key components.
“The ‘pod’ configuration is essentially a distributed fuel cell propulsion system that delivers thrust to the aircraft via six propulsors arranged along the wing,” explains Matthieu Thomas, ZEROe Aircraft Lead Architect. “Hydrogen fuel cells have very different design considerations, so we knew we had to come up with a unique approach.”
Indeed, hydrogen fuel cell technology has yet to be scaled up to a passenger-size large commercial aircraft. Smaller experimental hydrogen aircraft, comprising up to 20 seats, can rely on a traditional fixed-wing configuration with two propellers. But more passenger capacity and longer range require another solution. This is why Airbus is studying a variety of configurations, including “pods,” to determine which option has the potential to scale up to larger aircraft.
Strenghtens Rolls-Royce’s market position in safety-critical applications with a leader in dynamic uninterruptible power supply
Completes Rolls-Royce’s product offering and accelerates the strategy of offering integrated solutions
Acquisition expected to deliver cost and revenue synergies, and help support medium-term profitability and create long-term shareholder value
Rolls-Royce is strengthening its business in power supply for safety-critical systems with the completion of the acquisition of Kinolt S.A., a Belgian-based specialist in dynamic uninterruptible power supply. Rolls-Royce is already a leading provider of back-up power generation through its Power Systems business with its product and solutions brand MTU. This market has remained a growth area during the Covid-19 pandemic and is expected to grow in the coming years as customers look to further minimize their risk of disruption.
Uninterruptible power supply systems are used wherever stable electricity is required or a power failure would be extremely harmful, for example within data centres, hospitals or manufacturing facilities which operate sensitive processes. This acquisition is another important step on the strategic journey of Power Systems towards becoming a full-service provider of integrated solutions. Kinolt’s uninterruptible emergency power supply technology is particularly well suited to applications where space is at a premium, such as urban areas or installations in existing buildings and complements Rolls-Royce’s own MTU branded solutions for large scale and greenfield sites. As a result, the deal is expected to result in cost and revenue synergies, medium-term long-term shareholder value in the back-up power generation business.
Andreas Schell, CEO of Rolls-Royce Power Systems, said: “The extraordinary times created by the Covid-19 pandemic have shown just how important it is to secure electricity supply to sensitive and critical infrastructure. The provision of uninterruptible power is vital in any situation and even more so today, as it ensures the provision of vital services such as medical care or the world’s continued flow of internet traffic. Without it, no public authority or company would be able to act in any crisis.”
The demand for uninterruptible power solutions is expected to remain strong in the aftermath of the Covid-19 pandemic. The acquisition of Kinolt will give Rolls-Royce a market-leading solution for businesses and local authorities who experienced issues with supply, or do not wish to run the risk again.
“We originally signed the deal to acquire Kinolt before the full global impact of Covid-19 was apparent,” added Schell. “Since then we have rigorously examined the rationale for the transaction and the opportunities it presents to our business and concluded that the arguments in favour of the acquisition are even stronger than before.”
Power Generation is already the top-selling segment within the Power Systems business. In the future it is expected to be the only manufacturer in the world able to supply customers with all components and consequently a complete uninterrupted power generation system in the power range from 200 to 3,200 kVA. Kinolt’s technology consists of a combination of rotating, kinetic mass storage devices, a diesel engine and a generator that can also be used as an electric motor. MTU engines from Rolls-Royce are often already used within Kinolt’s solutions. The Kinolt system is connected between the external power supply system and safety-critical equipment and supplies the latter with the required electrical power during normal operation. The grid frequency and voltage are generally more stable than the grid of public power suppliers. This is necessary because data servers, computer-controlled systems or sensitive devices such as those in hospitals can fail in the event of voltage and frequency fluctuations. In the case of a power failure, the flywheel mass accumulator ‘bridges’ the first few seconds before the diesel engine takes up the load.
“We will integrate the products and systems of our new subsidiary into our MTU product portfolio,” said Andreas Görtz, Vice President of Power Generation at Rolls-Royce. “Our worldwide sales and service network will open up new market opportunities by offering innovative uninterruptible power solutions. This will significantly strengthen our market position in safety-critical applications.”
Kinolt is based in the town of Grâce-Hollogne in the Belgian province of Liège and was known as Euro-Diesel until mid-2019. The transaction was completed on 1 July 2020 following the approval of antitrust authorities.
