Manned Electric Aircraft Market 2017-2027 & 2031: Hybrid & Pure Electric Technology Roadmap, Market Forecasts, Companies, Models, MEA

Dublin, April 06, 2017 (GLOBE NEWSWIRE) -- Research and Markets has announced the addition of the "Manned Electric Aircraft 2017-2027 Hybrid & Pure Electric Technology Roadmap, Market Forecasts, Companies, Models, MEA" report to their offering.

The coverage in the report includes 2017-2027 forecasts of low and high priced electric aircraft sales by number, unit price and market value and a view of figures up to 2031 including assessments by several leading players. The subject matter includes looking at how electric aircraft have largely followed electric land and water vehicles. Pure electric small ones appeared first, about 50 years after the first electric boats and cars. Hybrid ones are needed for the longer distances and tougher duty cycles and only now are these getting serious investment.

The report finds that the delays are only partly explained by the tougher demands and regulatory requirements of aircraft and how things are now changing with much larger commitments. In 2016, Siemens and Airbus agreed to pool 200 engineers to work on them, the level of effort Toyota allotted to hybrid cars twenty years earlier, with major commercial success resulting today. Toyota enjoys well over $20 billion dollars of sales of electric cars, buses and forklifts with Honda and BMW successful too - interesting because all three are now tackling aircraft. Indeed, Google and Facebook are involved in electric cars and aircraft and Apple is interested so it is wake up time. The report analyses the opportunities in new aircraft and their changing key components.


This report of over 190 slide format pages is replete with new forecasts, analysis and infographics seeing the future. The key parts of recent presentations by all the key players are embedded in this work, almost entirely researched in 2016 and early 2017 by award winning PhD level analysts travelling worldwide. Interviews, analyst databases, web searches and conference attendance were extensively used. Old information is useless in this now fast moving field.

The LEMV is a hybrid airship - it's heavier than air, 80% of its lift coming from buoyancy and 20% from aerodynamics. Propulsion comes from six thrusters - three per side - powered by individual turbo-diesels for take-off and climb, and electrically from a central turbo-generator for loiter. And it's non-rigid, structural stability results from the three-lobe envelope design. The airship is also optionally piloted - flown manned for self-deployment and unmanned for persistent ISR missions.

Rise of the “Blimps”: Northrop Grumman's LEMV Program Completes Critical Design Review

Analysis by Defence Industry Daily Here: http://www.defenseindustrydaily.com/Rise-of-the-Blimps-The-US-Armys-LEMV-06438/


Press Release Below_


Fourth Major Milestone Completed; Next Major Milestone is Hull Inflation

MELBOURNE, Fla., BETHPAGE, N.Y., and LONDON – Feb. 1, 2011 – Six months after signing the Long Endurance Multi-Intelligence Vehicle (LEMV) agreement with the U.S. Army to build three airships with 21-day persistent intelligence, surveillance and reconnaissance (ISR) capability, Northrop Grumman's (NYSE:NOC) LEMV program team has completed its Critical Design Review (CDR). This is the fourth major milestone achieved by the program since contract award.

"The entire U.S. Army/Northrop Grumman LEMV industry team has done an outstanding job working through a very aggressive development schedule to achieve all of these important milestones. The CDR provided an in-depth review of the complete system design of the program giving us the opportunity to assess where we are in our development and air vehicle production. It went very well," said Alan Metzger, Northrop Grumman vice president and integrated program team leader of LEMV and airship programs. "The entire team has been collaborating and remains very focused on meeting our objective of delivering this powerful capability into the hands of our combat commanders as soon as possible."


"There are three upcoming major milestones in the next 10 months," Metzger said, "We'll have hull inflation in the spring and first flight of the airship test article by mid-to-late summer. Upon completion of the development ground and flight testing phase, we expect to transition to a government facility and conduct our final acceptance long endurance flight just before year's end. In early 2012, LEMV will participate in an Army Joint Military Utility Assessment in an operational environment," he added. "As you can imagine, it's a very aggressive schedule to deliver from concept-to-combat in this time period."

Under the June 2010 agreement, awarded by the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command, Northrop Grumman will design, develop and test a long-duration hybrid airship system all within an 18-month time period.

"The power of the LEMV system is that its persistent surveillance capability is built around Northrop Grumman's open architecture design, which provides plug-and-play payload capability to the warfighter and room for mission growth," Metzger said. "The system rapidly accommodates next-generation sensors as emerging field requirements dictate and will provide increased operational utility to battlefield commanders. Today, our system readily integrates into the Army's existing Universal Ground Control Station and Deployable Common Ground System command centers and ground troops in forward operating bases.

"Beyond the value of seamless interoperability, the LEMV system provides a high level of fuel efficiency to the user community—a crucial part of life cycle logistics and support in theatre.  While LEMV is longer than a football field and taller than a seven-story building, it utilizes approximately 3,500 gallons of fuel for the air vehicle to remain aloft for a 21-day period of service, that's approximately $11,000 at commercial prices," Metzger added.

Northrop Grumman's industry team includes Hybrid Air Vehicles, Ltd. of the United Kingdom, Warwick Mills, ILC Dover, AAI Corporation, SAIC and a team of technology leaders from 18 U.S. states and three countries. In addition to leading the program, Northrop Grumman leads the system integration, and flight and ground control operations for the unmanned vehicle to safely take off and land in worldwide operations.

Northrop Grumman Corporation is a leading global security company whose 120,000 employees provide innovative systems, products, and solutions in aerospace, electronics, information systems, shipbuilding and technical services to government and commercial customers worldwide.
