Workhorse SureFly
The SureFly is a two-seat hybrid eVTOL aircraft designed by American truck-manufacturer Workhorse Group, before the program was bought by Moog Inc. for $5 million in December 2019. Design The hybrid electric has a 200-hp gasoline generator giving up to range over 1 hour. It has four propeller arms, each with two electric contra-rotating propellers powered by a gas turbine or piston engine generator along with a battery pack. Targeting a price of $200,000, it can lift a payload and includes a ballistic parachute. The SureFly would operate as a conventional helicopter, like the similarly priced two-seat Robinson R22, but would be easier to fly and safer with its integral parachute. SureFly has taken refundable $1,000 deposits but does not specify a delivery date, and aims to produce 1,000 per year. The hybrid design is simpler than a pure gasoline drivetrain by eliminating the gearboxes and rotor linkages of a traditional helicopter, while security is higher through two redund ...

Electric Helicopter
An electric aircraft is an aircraft powered by electricity. Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights. Electricity may be supplied by a variety of methods, the most common being batteries. Most have electric motors driving propellers or turbines. Crewed flights in an electrically powered airship go back to the 19th century, and to 1917 for a tethered helicopter. Electrically powered model aircraft have been flown at least since the 1970s, preceding the small unmanned aerial vehicles (UAV) or drones used today. Small UAS could be used for parcel deliveries, and larger ones for long-endurance applications: aerial imagery, surveillance, telecommunications. The first crewed free flight by an electrically powered aeroplane, the MB-E1, was made in 1973, and most crewed electric aircraft today are still only experimental prototypes. Between 2015 and 2016, Solar Impulse 2 completed a circum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airbus A³ Vahana
The Airbus Vahana (Sanskrit: ''Vāhana'', or Vahanam literally means "vehicle") was an electric-powered eight-propeller VTOL personal air vehicle prototype financed by A³ (pronounced "A-cubed"), by Airbus and Airbus Urban Mobility. The Vahana project started in 2016 as one of the first projects at A³, the advanced projects and partnerships outpost of Airbus Group in Silicon Valley. Airbus "envision Vahana being used by everyday commuters as a cost-comparable replacement for short-range urban transportation like cars or trains". It was planned to be a part of urban air mobility. The project was finished in December 2019. Development The convertiplane aircraft design, funded by the European aircraft manufacturer Airbus, called Vahana (Sanskrit: "vehicle"), started in 2016. It was being developed at A³ (A-cubed), the expanded project and partnership outpost of Airbus in Silicon Valley. Airbus said "Our work on this demonstrator confirms our belief that fully autonomous veh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Air Vehicle
A personal air vehicle (PAV) is a proposed type of aircraft providing on-demand aviation services. The emergence of this alternative to traditional ground transport methods has been enabled by unmanned aerial vehicle technologies and electric propulsion. Barriers include aviation safety, airworthiness, operating costs, usability, airspace integration, aircraft noise and emissions, tackled first by small UAS certification then experience. Definition The personal air vehicle (PAV) is intended to provide flight convenience similar to the private car in terms of accessibility and ease of operation, while also offering the speed and routing efficiencies made possible by direct point-to-point flight. The PAV differs from conventional general aviation types and flying cars in being usable by people with no pilot qualifications. History NASA established the Personal Air Vehicle Sector Project in 2002, as part of their Vehicle Systems Program (VSP). This project was part of the NASA ...

Passenger Drone
Unmanned aerial vehicles (UAVs), commonly known as drones, have seen an uptick is usage in the early 1990’s. This technology can be used for data collection and analysis, surveillance, research, filmmaking, and other general usage, and although it was once reserved for military use through the 1990’s and early 2000’s, it now has usage among civilians. Since the 2000s, drone technology has improved to include developments in commercial applications such as deliveries and passenger transportation. More specifically, Ehang, a technology company based in Guangzhou, China, has developed the Ehang 184, the world's first passenger drone. These advancements in drone technology have led to many more developments and usage in the aspect of passenger transportation. History Unmanned aerial vehicles were first introduced in World War 1, when Britain first developed the Aerial Target, an aircraft controlled remotely through radio signals. A year later in the United States, testing of Ketter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corporate Spin-off
A corporate spin-off, also known as a spin-out, or starburst or hive-off, is a type of corporate action where a company "splits off" a section as a separate business or creates a second incarnation, even if the first is still active. Characteristics Spin-offs are divisions of companies or organizations that then become independent businesses with assets, employees, intellectual property, technology, or existing products that are taken from the parent company. Shareholders of the parent company receive equivalent shares in the new company in order to compensate for the loss of equity in the original stocks. However, shareholders may then buy and sell stocks from either company independently; this potentially makes investment in the companies more attractive, as potential share purchasers can invest narrowly in the portion of the business they think will have the most growth. In contrast, divestment can also sever one business from another, but the assets are sold off rather t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Certification
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, primary category aircraft, certification costs around US$1m, US$25m for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes. The TC reflects a determination made by a regulatory authority that the type desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Envelope
In aerodynamics, the flight envelope, service envelope, or performance envelope of an aircraft or spacecraft refers to the capabilities of a design in terms of airspeed and load factor or atmospheric density, often simplified to altitude. The term is somewhat loosely applied, and can also refer to other measurements such as maneuverability. When a plane is pushed, for instance by diving it at high speeds, it is said to be flown "outside the envelope", something considered rather dangerous. Flight envelope is one of a number of related terms that are all used in a similar fashion. It is perhaps the most common term because it is the oldest, first being used in the early days of test flying. It is closely related to more modern terms known as extra power and a doghouse plot which are different ways of describing a flight envelope. In addition, the term has been widened in scope outside the field of engineering, to refer to the strict limits in which an event will take place or mor ...

Flight Test
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or Atmosphere of Earth, atmospheric testing of launch vehicles and Reusable launch vehicle, reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to Verification and validation, validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any Aeronautics, design problems and then 2) verification and validation, verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a ...
