The Flying Car Of the Future Looks to Flying Cars of the Past

The Air Force is close to testing an experimental vertical takeoff prototype under its new program.

The first contract in the U.S. Air Force's bid to acquire flying cars has gone to a company whose design harks back to a pioneer in the field.

California-based Sabrewing Aircraft Company received a $3.25 million Phase II Small Business Innovative Research earlier this month to test its Rhaegal-B, a four-rotor craft that the company says can carry up to 5,400 pounds up to 200 knots some 1,000 nautical miles.

With its four electric rotors, two on either side of the aircraft, the 60-foot Rhaegal-B somewhat resembles the M400X Skycar from Paul Moller.

Moller is, in many ways, the Nikola Tesla of the flying car field. In the early 2000s, the Moller International Skycar became the first non-helicopter vertical takeoff and landing aircraft to actually get off the ground. The four motors would lift the car up and then swivel to propel it forward, like a V-22 Osprey. Even though the design worked, it never made it into showrooms.

“For the engine, the most critical element is power,” Moller told The Futurist magazine in 2008.

“Once you reduce the diameter of the propulsion system [making the propellor smaller] you go from a helicopter to a fan system. So you're moving less air, and the less air you move, the more power it takes to generate a certain kind of thrust. If I took a helicopter and made it one-half the diameter, I would have to immediately add 60% more power. I halve the diameter again, I have to add 60% more power, again. The M400 Skycar has over 1,000 horsepower.”

Given the high cost to power it, the M400 Skycar was impractical for most locations outside of the Middle East, where oil sheiks would use them to traverse wide distances, Moller said at the time.

Sabrewing CEO Ed De Reyes, who once worked for Moller, said his former boss was restricted by the engines of his time. The best-suited for the purpose were Wankel rotor engines, and internal combustion engines, which offered high speeds but limited torque. The electric motors that have arrived in recent years are far more promising: smaller, lighter, yet capable of producing more torque than an internal combustion engine.

The Rhaegal-B design is highly but not fully autonomous, De Reyes said. A controller will command it from a ground station, but with the sort of low-effort, push-button interface you would encounter on a Northrop Grumman Global Hawk, rather than the more hands-on piloting needed for General Atomics MQ-9 Reapers.

Something else that's come a long way since the early 2000s is the ability to detect and avoid objects in mid-air. Ssense-and-avoidance systems are a major stepping stone to more widespread use of drones in U.S. civilian airspace. A lot of drone manufacturers are hoping for the FAA's blessing for their versions.

The Rhaegal-B combines radar and nine other sensors to give the aircraft a picture of the environment around it. It can take evasive action without any human control. (In fact, humans can't override it to accidentally steer the vehicle into something else.) If communication is cut off, it can continue to its destination with no additional imput from the ground operator.

The appeal for the Air Force has to do with versatility and even detectability. During a webcast on Monday, Air Force Col. Pete White, with Air Force Warfighting Integrating Capability, said that traditional helicopters are noisy compared new vertical-lift aircraft. Thanks, in part, to the new electric motors. “Within feet of an enemy, they can't hear you,” He said that new, nimble electric air vehicles that could take off and land without a runway could help the military “maneuver around the battlefield at a pace that would be impossible today”

The Air Force says it wants flying cars to evacuate wounded soldiers from the battlefield, among other missions. That means that they could be operating under fire. De Reyes says the military version of the aircraft has a Kevlar coating to protect it from small ballistics and can operate even when one of the motors is damaged.

Air Force officials have also said that they are looking to fund and support U.S. flying-car companies, lest they migrate to China or accept lots of foreign investment. De Reyes says he's often approached by Chinese investors looking to gain a foothold in his company and other entrepreneurs in this space are as well.

Sabrewing will test the Rhaegal-B at the Air Force's Edwards Air Force Base, hoping to meet safety requirements that will clear it for more military work and perhaps even commercial use. A June flight demonstration with its prototype has been postponed due to travel restrictions

    US spy planes are breaking down ― and lawmakers want answers

    By: Joe Gould WASHINGTON ― America's aging C-135 reconnaissance planes keep breaking down, and alarmed lawmakers want the U.S. Air Force to tell them why. Based at Offutt Air Force Base, Nebraska, the 55th Wing's Boeing-made reconnaissance and intelligence-gathering aircraft, all more than 50 years old, are meant to carry out critical missions from operating bases in England, Greece, Japan and Qatar. But an Omaha World-Herald investigative series has found that mechanical problems plague the jets, cutting short 500 of their flights since 2016 and one of every 12 missions since 2015. That's prompted Nebraska lawmakers to write to Air Force Secretary Heather Wilson, urging her to probe and report on the health of the 55th Wing's worn-out fleet. Meanwhile, the Nebraska delegation is trying to fend off an effort within Congress to strip funding to recapitalize the OC-135, which conducts overflights of Russia under the 34-nation Open Skies Treaty. Some lawmakers and Pentagon officials have grown skeptical of the treaty, which allows reciprocal surveillance flights, amid alleged Russian violations, but the administration has requested funds for two new airliners to take over the mission. “It has one of the worst maintenance rates in the United States Air Force,” Rep. Don Bacon, R-Neb., said of the OC-135 on the House floor last week. “It frequently breaks down in Russia, putting us in very hostile, awkward situations with Russians at their bases.” The chair of the Senate Armed Services Committee's Strategic Forces Subcommittee, Deb Fischer, led the letter with Sen. Ben Sasse, a SASC member; Bacon (a retired brigadier general and former 55th Wing commander who sits on the House Armed Services Committee), as well as Reps. Jeff Fortenberry and Adrian Smith. The letter asked Wilson to report on the 55th Wing's safety, security and continued mission effectiveness as well as the Air Force's long-term plans to sustain and recapitalize the wing's capabilities. It referenced the RC-135V/W Rivet Joint, RC-135S Cobra Ball, RC-135U Combat Sent, WC-135 Constant Phoenix, TC-135 Rivet Joint Trainer and the OC-135 Open Skies aircraft. In the current budget season, House and Senate lawmakers have taken divergent approaches to the Trump administration's $222 million request for the two new aircraft. House appropriators and authorizers stripped the funding from their 2019 bills. The authorization bill withholds the funding until Russia adheres to the treaty and agrees to extradite Russians indicted for meddling in U.S. elections in 2016. Fischer helped ensure the Senate-passed 2019 authorization bill did include funding for OC-135 recapitalization, and the bill will have to be reconciled with its House counterpart. Defense Secretary Jim Mattis directed the Air Force to recapitalize the aircraft. He wrote to Fischer in May to acknowledge that unplanned maintenance issues meant the U.S. completed only 64 percent of its scheduled overflights in 2017, while Russia typically completes all of its scheduled overflights. The White House Office of Management and Budget has also issued letters objecting to the absence of OC-135 recapitalization funding in the House bills. https://www.defensenews.com/congress/2018/07/02/us-spy-planes-are-breaking-down-and-lawmakers-want-answers/

    An unpredictable autumn: Changes across Europe could spell delays for industry deals

    By: Tom Kington ROME — Just as Europe begins serious discussions about joint defense programs, Italy is scrambling to forge a new government, putting decision-making in Rome on hold amid Britain's exit from the European Union and a change of guard at the organization. Following the collapse of the Italian government last month, Rome is expected to have a new coalition majority in place this week, but the hiccup may further delay decisions about Italy's role in Britain's Tempest fighter program, European partnerships and purchasing of F-35 aircraft. The uncertainty in southern Italy matches the threat of chaos further north if British Prime Minister Boris Johnson carries out threats to leave the EU on Oct. 31 without a trade deal, just as the European Commission awaits a new crop of leaders following the EU election in May. “Defense programs are always prone to delays and cost overruns, but when they are joint programs, that risk increases — and now is a case in point,” said Aude Fleurant, the director of arms and military expenditure at the Stockholm International Peace Research Institute, a Swedish think tank. Origins and options Italy's government upheaval began in early August when one of the members of Italy's populist coalition government, the League party, walked away from the administration after too many policy rows with its partner, the Five Star party — ending the government's parliamentary majority. League party leader Matteo Salvini, whose anti-migrant policies have spurred his popularity after 14 months of government, hoped he could take sole command of the government through new elections. But his plan suffered a setback when Five Star entered talks with its sworn rival, the center-left Democratic Party, to build a new majority and carry on governing without the League. As a sign of open hostilities between the former coalition partners, Italian Defence Minister Elisabetta Trenta — who is backed by Five Star — sent Navy ships to escort vessels carrying rescued migrants in the Mediterranean Sea, much to the anger of League leader Salvini. With the likelihood that ministers for the new Five Star-Democratic Party coalition will be sworn in this week, it's unclear if Trenta will keep her post. Nevertheless, a new government will likely add further delay to Italy's decision on whether to join the U.K. Tempest program. That potential time frame adds to the months during which Trenta failed to decide on the program following its launch by the U.K. in 2018, despite pressure from Italian defense company Leonardo and behind-the-scenes talks between Italian and British military officials. In the meantime, Sweden has signed up, raising fears Italy will miss out on technological work. Trenta's hesitancy may have stemmed from the fact that the party that put her in office, Five Star, has mixed feelings about Italy's ongoing purchase of F-35 jets. During her time in office, the government prevaricated over fulfilling its planned order of 90 aircraft. Someone in Rome is needed to arbitrate in the row between the Navy and Air Force over who should manage the basing of the F-35B, which both forces are ordering. Analysts warned that Italy could miss its chance to snatch F-35 contracts that Turkey is losing as it's forced out of the program. One analyst said tension could escalate over the F-35 if and when a Five Star-Democratic Party coalition emerges. “Let's see who the minister is — that will make a difference,” said Alessandro Marrone, a senior fellow at the IAI think tank in Rome. A second analyst said that by divorcing from the right-wing League and teaming with the center-left Democrats, Five Star's skepticism toward the F-35 could become more pronounced. “I could imagine Five Star agreeing to pro-EU policies favored by the Democrats in return for blocking the F-35 program, or even agreeing to enter the Tempest program in return for blocking the F-35,” said the analyst, who spoke on condition of anonymity. A source with knowledge of the inner workings of the Italian government said the Democrats might also sacrifice the F-35 to win an agreement to build a rail line in northern Italy that Five Star opposed. Gabriele Iacovino, an analyst at the International Study Center in Rome, said: “Defense is always the last issue to be considered when a new government is formed, and the defense minister is always the last to be appointed.” Five Star did make one reference to defense in an Aug. 30 list of 20 policies it wants to pursue in a new coalition with the Democrats. “Put an end to the sale of armaments to war-waging countries, and incentive the process of converting industry,” the Five Star party stated, suggesting that parts of the Italian defense industry would be turned over to the production of civilian technology. But in a successive draft list of policies issued Sept. 3, the policy was missing, apparently dropped. Looking west At the other end of Europe, Brexit is creating uncertainty of a different kind for the continent, said Douglas Barrie, a senior fellow for military aerospace at the IISS think thank in London. “There are two kinds of challenge for the British defense community when it comes to Brexit: one is relationship management, the other about bureaucratic,” he said. “Relationship management is in part how ugly the U.K.'s departure is, and for how long the atmosphere is soured between London and its erstwhile partners in Brussels,” he added. “The bureaucratic issues include problems regarding the movement of goods and personnel within defense companies operating in or across Europe, and the ability to access, or not, European research and development funding.” That spells trouble for U.K. firms, but also for Italy's Leonardo, which has 7,000 staff in the U.K. after buying up large parts of the defense electronics industry there. If anything, Leonardo's challenge is twofold: It must keep channels open between its U.K. facilities and European markets, but also with its sister operations in Italy. “In the case of a no-deal [Brexit], how will Leonardo transfer parts and staff from its U.K. to its Italian operators?” said the source knowledgeable of the Italian government's inner workings. Speaking to Defense News in March, Leonardo CEO Alessandro Profumo said it would be crucial to know where the intellectual property for a product must be registered so it can secure development funding from the EU. “There is also an upside since having a base in the U.K. could help Leonardo when it comes to deals with the U.S. and help counterbalance the hegemony of France and Germany in Europe,” said Iacovino, the analyst in Rome. Furthermore, if political crises and Brexit are bumps in the road for Italy and the U.K., defense cooperation between France and Germany is certainly not going smoothly, said Aude Fleurant at SIPRI. “The French-German plans for a sixth-generation fighter, FCAS, are being held up by significant differences over exports to the Middle East,” she said. “France is very unhappy over Germany's opposition, and Germany is refusing to budge.” https://www.defensenews.com/digital-show-dailies/dsei/2019/09/08/an-unpredictable-autumn-changes-across-europe-could-spell-delays-for-industry-deals
