eVTOL development company Overair announced today the appointment of Tom Whayne as chief financial officer (CFO). As CFO, Whayne will oversee all financial operations and provide strategic guidance to the company as it continues its path toward commercialization.

Whayne joins OverAir having previously served as chief financial officer of OneWeb, where he led the raise of more than $3 billion of capital to fund the company’s development of a global broadband communications constellation in Low Earth Orbit. Most recently, he was senior vice president and chief strategy officer of Maxar Technologies, an Earth intelligence and space infrastructure company.

“We are immensely proud to welcome Tom to the team,” said Ben Tigner, co-founder and CEO of Overair. “His finance and operating background in orbital platform companies positions him perfectly to help Overair prepare for rapid scaling. Tom’s appointment comes at a pivotal time in our company as we build our full-scale Butterfly prototype.”

In addition to Whayne’s tenure at OneWeb and Maxar, he brings over 20 years of experience as an investment banker. Whayne was a managing director at Credit Suisse First Boston, Morgan Stanley, and Rothschild. He has a bachelor’s degree in economics from Harvard College and a J.D. degree from the University of Virginia School of Law.

Adding Whayne to the team solidifies the strength of Overair’s C-suite and continues the momentum of the company which has made significant progress in the development of its Butterfly aircraft, with full-scale propulsion testing completed in the second quarter of 2022 and current execution of its full-scale prototype program in 2023.

Why it’s important: Overair currently markets the Butterfly as the quietest, most robust and largest-capacity production-eVTOL vehicle and intends for their aircraft to have seating for five passengers and a pilot plus a separate large cargo compartment. The appointment of Tom Whayne will help the company stay its course during capital intensive research and development phases on the road to certification of their eVTOL aircraft.

Overair, Inc. and Toray Composite Materials America have announced a strategic collaboration for utilization of Toray’s advanced prepreg system in Overair’s Butterfly eVTOL prototype program.

Above: Rendering of Overair’s Butterfly eVTOL prototype with Toray T1100/3960 carbon fiber/epoxy prepreg. The prepreg provides high stiffness and strength for the prototype’s airframe and propulsion units.

The airframe of Overair’s Butterfly eVTOL prototype utilizes Toray’s T1100/3960 prepreg system, a material that is formulated for high-performance aerospace applications where the optimal ratio of strength to modulus properties is critical. Toray’s 3960 is a highly-toughened 350°F/177°C cure epoxy resin with a glass transition temperature (Tg) of 400°F/204°C. It is optimized for increased performance and allows for autoclave and out-of-autoclave curing. The resin is synergistic with the TORAYCA™ T1100 next-generation intermediate modulus plus (IM+) carbon fiber, which is the highest tensile strength fiber available today. The T1100/3960 unidirectional and plain weave prepreg is utilized both in the Butterfly’s airframe structure and propulsion units.

“We’re excited to be working closely with Toray’s advanced materials as we continue the development of our all-electric Butterfly experimental prototype aircraft,” said Ben Tigner, Co-Founder and CEO at Overair. “Our unique propulsion system requires materials that provide a unique combination of high stiffness and high strength, while also maintaining the optimal weight targets for the vehicle.”

Overair recently completed full-scale testing of the Butterfly’s propulsion system. The successful testing program validated Overair’s design choices and the Butterfly’s expected performance capabilities. The Butterfly’s prototype propeller will be showcased at the Farnborough International Air Show from July 18 to July 22 in Farnborough, England.

“It is an honor for Toray to partner with Overair on this endeavor and provide the Butterfly a unique performance advantage with our 3960 prepreg system,” according to Jeff Cross, Director of Business Development for Aerospace at Toray. “We’re excited for the future as Overair proceeds with full-scale development and testing. The proven performance of our materials gives me confidence that we can help achieve Overair’s objective of producing the safest, most efficient, and reliable eVTOL aircraft.”

Why it matters: Tacoma, Washington based Toray has a long time partnership with Boeing on the 777/777X and 787 programs with extensive experience in advanced composite manufacturing for aerospace applications. Next-generation materials from Toray will provide Overair’s prototype with excellent physical properties while minimizing weight and maximizing payload and vehicle range.

Electric vertical takeoff and landing vehicle (eVTOL) company, Overair, just announced its most recent funding of $145 million from Hanwha Systems and Hanwha Aerospace, global leaders in ultra-precision communications and aircraft technologies. With this new investment, Overair claims that it remains on track to fly its all-electric experimental prototype in the second half of 2023.

“This is a tremendous milestone for our growing team, and we’re extremely well positioned to deliver sustainable aerial ridesharing to the world through the development of Butterfly,” said Ben Tigner, Co-Founder and CEO of Overair. “We’re exactly where we want to be, building a superior aircraft company with class leading mobility technology around an unrivaled aircraft while rapidly approaching the first flight of a purpose-built prototype next year. We’ve proven Butterfly’s propulsion system, so we’ll now begin validating Butterfly’s ability to operate safely in real-world weather conditions, carry significant payloads, and fly incredibly quietly.”

Butterfly is an all-electric aircraft with six seats designed to take off and land vertically. The aircraft’s advanced propulsion system is derived from decades of military VTOL programs led by Abe Karem. Thanks to this legacy of proprietary engineering, Butterfly’s propulsion is extremely efficient and is claimed to give Butterfly the broadest flight envelope and smallest sound footprint of any aircraft in the burgeoning industry. Specifically, Butterfly’s unique Optimum Speed Propulsion (OSP) uses four large propellers, which spin slowly when hovering and even slower when cruising, and draw only a fraction of the available motor power, giving Butterfly extra payload capacity and power margins to operate safely in challenging environmental conditions. Additionally, the slow-turning props produce extraordinarily little sound, which will allow Butterfly to operate in high-density areas with noise sensitive communities.

“Hanwha’s basic principles for new business development is to focus on ‘Disruptive Innovation’ that can uproot and shift the market and technology trends based on its core capabilities. In alignment with its core capabilities as well as its main businesses, Hanwha is selecting ‘Game Changer’ businesses that it can really excel in the future, and eVTOL vehicle is one of the ‘Game changer,'” said Mr. Sungchul Eoh, CEO of Hanwha Systems. “With regard to our investment decision in Overair, we assessed that the company had the numerous patients and core technologies required to develop highly efficient, low noise vehicle. Therefore, we expected that Overair would be capable of developing superb vehicle that can satisfy the requirements for safety, efficiency, speed, low noise, and environment-friendly feature. We see the potential of Overair’s Optimum Speed Propulsion system and we will continue to work together to find synergies and bring this breakthrough technology to the world.”

As the company continues to work toward FAA certification, Overair is also working with NASA and Urban Movement Labs in Los Angeles to develop urban air mobility (UAM) routing and infrastructure. 

Why it’s important: Hanwha’s continued investment in Overair not only fuels the ongoing development of Butterfly but will also allow Overair to lay the groundwork for commercializing their mobility technology. In addition to their investment, Hanwha will also provide electric motors and battery packs for Overair’s prototypes, as the two companies expand their R&D co-operation.

Overair has recently released new details about their new electric VTOL air taxi, dubbed the Butterfly. Built to withstand rough weather conditions, the 6-seater aircraft will have a range of 100 miles and a top speed of 200 mph. In addition, the Butterfly will be all electric and have zero carbon emissions. The key feature of the Butterfly’s design is the propulsion system. With four large propulsors, the Butterfly’s propulsion system has a large disk area, allowing it to use less power in VTOL mode and make it more efficient overall. 

According to Ben Tigner, CEO of Overair, “Our fundamental technology advantage, the propulsion, that we bring to the party here is inherently more efficient. We get more thrust for less power, that’s why we’re able to go battery only, not needing the hybrid solution. So we have larger rotors, larger propulsors than most other people in the industry so we can generate the thrust unit for flight, using less kilowatts and less kilowatt-hours.”

The aircraft’s design also factors in noise emissions reductions, according to Tigner. The large disk area allows for minimal pressure disturbances from the system, which generates less noise during flight compared to other similar sized aircraft. 

“It’s also going to be very very quiet,” said Tigner, “We anticipated that will be the quietest eVTOL vehicle in the field, and that is based on the fact that it has the largest rotors in the field and we’re able to spin the rotors very slowly. Not only is the amount of sound, the intensity of the sounds generated by the propulsion system very low, but also the character of the sound is such that the frequency projected is at a place where the human ear is very insensitive. So it really should be an extraordinarily quiet aircraft, quieter than anything else that’s out there in the industry right now.”

The Butterfly will officially debut as a piloted eVTOL air taxi, capable of flying 5 passengers or a cargo payload of 1,100 lb. However, Overair has plans to implement automated flight in the future. For this purpose, the Butterfly will start out equipped with a full authority fly-by-wire system that provides an avenue for future automated flight. According to Tigner, “We’ve adopted an approach that really bites down on the notion of simplified vehicle operation where we’ve sort of adopted the view that you should have an interface…is a smooth transition between hover control and or flight control in a mode, similar to what you see on the F-35, you know, the unified command approach that defines how the sticks translate from hover controlling to into forward flight control. The fly by wire system, by virtue of the fact that it is full authority, has the ability to implement important envelope protections that prevent the vast majority of human error type accidents.” 

The company expects the prototype model of the Butterfly to first take flight next year, and to receive FAA certification sometime in 2025. As of now, Overair anticipates that their main areas of commercial operation will be in the United States and South Korea.
