Aurora Unveils High-Speed VTOL X-Plane Concept Design

Aviation Week reports, “Aurora Flight Sciences on Oct. 8 unveiled new details of a notional operational variant of the fan-in-wing concept it is proposing for a high-speed, vertical-takeoff-and-landing (VTOL) X-Plane. The operational version of the Boeing-owned company’s candidate for a DARPA demonstrator program would boast nearly the same wingspan and payload weight of a Lockheed Martin C-130J, yet fly up to 90 kt. faster and be able to take off and land vertically like a helicopter.”

DARPA Announces 6 New Designs for Uncrewed VTOL Military Aircraft

SPACE reports, “The U.S. military could soon have new uncrewed aircraft that carry weapons and take off and land vertically. The vehicles could undergo test flights as early as 2026. The Defense Advanced Research Projects Agency (DARPA) has announced it is moving into a new testing phase for proposed experimental aircraft in which designs will be assessed for risk and analyzed for efficiency.”

Sikorsky Performing Flight Trials for VTOL Tail-Sitter UAS

Unmanned Systems Technology reports, “Sikorsky, a Lockheed Martin company, is carrying out flight tests to mature the control laws and aerodynamics of a novel vertical takeoff and landing uncrewed aerial system (VTOL / UAS). The flight tests aim to prove the efficiency and scalability of a twin proprotor ‘rotor blown wing’ configuration, designed to sit on its tail to take-off and land like a helicopter, and transition easily to horizontal forward flight.”

EASA Publishes Noise Standards for EVOTLs

Aviation International News reports that EASA “has published what it claims are the world’s first proposed noise certification standards for eVTOLs.” The proposals, known as the Environmental Protection Technical Specifications (EPTS), “are applicable to eVTOL vehicles powered by multiple vertical, non-tilting, evenly distributed rotors.” EASA says that the proposed specifications “are intended to fill a regulatory gap and use the internationally harmonized noise certification standards for heavy helicopters” as a starting point while it “collects more noise data from specific eVTOL designs through certification projects.” In addition, a hover noise level “has been developed to aid in the assessment of flight operations in the vicinity of vertiports.”

A new wave of aerospace entrepreneurs and technology startups are stepping in to try and solve the problem of traffic, and according to a panel of experts at the 2017 AIAA AVIATION Forum in Denver, it could be done with vertical takeoff and landing, or VTOL, aircraft.

As any commuter knows, roadway congestion eats up a huge amount of time and energy, and “traffic is taking over our lives,” Jon Rimanelli, founder and CEO of AirspaceX, said during the discussion June 8.

Rimanelli cited figures showing that each driver loses about $1,400 in fuel costs and productivity each year due to traffic.

“Key to this future is leveraging the automotive industrial base,” he said, adding that his company works with Uber, which has disrupted the taxi and car markets with its ridesharing app.

“Our mission is to support Uber, and their mission is to move people,” Rimanelli said.

Mark Moore, director of aviation at Uber Engineering, said his company’s working on making electric VTOL a reality and plans to tests the system as soon as 2020.

“Uber is going to connect the users to the network. Uber is a software company, and there is a great deal of software in this ecosystem,” Moore said. “Uber will be very active in developing the network, including the network operations center.”

But, Moore insists, “We see many participants in this system.”

One such example is Pipistrel, whose director of research and development, Tine Tomažič, explained where electric flight is at in terms of development today.

“We understand what happens when you are really challenged with power demands,” Tomažič said.

However, he said, some of the problems that still need to be solved before e-VTOL is a reality on a mass scale aren’t directly related to the vehicles themselves.

“When these vehicles are connected all the time to the service network, one has to think, ‘how do you isolate the vehicles from cyberattacks?’” Tomažič said.

Other obstacles panelists noted are potential objections from local governments or federal regulators.

“You have to make the case that the tradeoff between noise to the community and benefit to the community is positive,” said David Josephson, engineer and CEO of Josephson Engineering Inc.

Greg Bowles, vice president of global innovation and policy at the General Aviation Manufacturers Association, said he’s skeptical the infrastructure is ready for e-VTOL on a mass scale.

“When we talk about the needs of charging one of these vehicles in five minutes, it’s like adding a grocery store to the grid for five minutes,” Bowles said.

Despite these risks, even large companies like Airbus are investing in e-VTOL technology, said Geoffrey Bower, chief engineer of A^3 at Airbus Group.

“We’re trying to disrupt Airbus and the rest of the aerospace industry before somebody else does,” he said. “The technology, the components are there; we just need the integration.”

Rimanelli urged regulators: “What we need you to do is collaborate, partner or get out of the way.”
