Boeing Cargo Air Vehicle
The Boeing Cargo Air Vehicle is an unmanned, autonomously flying, fully electric cargo air vehicle (CAV). It was made possible by an investment of Boeing HorizonX Ventures. Development At the beginning it was remote control-operated. Later it flew autonomously. The first flight tests have been in 2017. The CAV is for research of autonomy technology for aerospace vehicles in the future. In Boeing's Ridley Park wind tunnel flight tests have been finished. It was flying indoor in 2018 before outdoor flights in 2019. With the Boeing CAV there are new possibilities for the transport of time-sensitive and high-value goods and to conduct autonomous missions in remote or dangerous environments. Its configuration evolved to six dual-rotor systems with 12 propellers and the first outdoor flights tests were done by May 2019, including forward flight transition. By September 2020, Boeing was to close its Boeing NeXt division, in response to financial losses in the wake of the 737 MAX grou ...

VTOL
A vertical take-off and landing (VTOL) aircraft is one that can take off and land vertically without relying on a runway. This classification can include a variety of types of aircraft including helicopters as well as thrust-vectoring fixed-wing aircraft and other hybrid aircraft with powered rotors such as cyclogyros/cyclocopters and gyrodynes. Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off & landing), STOL (short take-off & landing), or STOVL (short take-off & vertical landing). Others, such as some helicopters, can only operate as VTOL, due to the aircraft lacking landing gear that can handle taxiing. VTOL is a subset of V/STOL (vertical or short take-off & landing). Some lighter-than-air aircraft also qualify as VTOL aircraft, as they can hover, takeoff and land with vertical approach/departure profiles. Electric vertical takeoff and landing aircraft, or eVTOLs, are being developed along with more autonomous flight control tech ...

Micro Air Vehicle
A micro air vehicle (MAV), or micro aerial vehicle, is a class of miniature UAVs that has a size restriction and may be autonomous. Modern craft can be as small as 5 centimeters. Development is driven by commercial, research, government, and military purposes; with insect-sized aircraft reportedly expected in the future. The small craft allows remote observation of hazardous environments inaccessible to ground vehicles. MAVs have been built for hobby purposes, such as aerial robotics contests and aerial photography. Practical implementations In 2008, the TU Delft University in the Netherlands developed the smallest ornithopter fitted with a camera, the DelFly Micro, the third version of the DelFly project that started in 2005. This version measures 10 centimeters and weighs 3 grams, slightly larger (and noisier) than the dragonfly on which it was modeled. The importance of the camera lies in remote control when the DelFly is out of sight. However, this version has not yet b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Helicopters
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of ...

Electric Aircraft
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 circ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2010s United States Experimental Aircraft
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natilus
Natilus is a Californian startup company developing seaplane UAVs to ship air cargo. Market Natilus targets an existing $100 billion per year Trans-Pacific airfreight market, growing due to e-commerce and as 30% of US companies sales are international. In 2015 it planned to initially operate a fleet of up to five cargo planes with one partner per route and offering the cargo insurance for the first year, saving operational costs for freight forwarders and increasing the profit margin by 20%. Natilus hopes to build hundreds of the drones, to operate itself under its customer brands or to sell them directly to customers like UPS and FedEx or “medium freight forwarders” like Whole Foods and Costco. It would cost about one-tenth of a crewed freight aircraft, and transoceanic trips would cost about half as much as standard air freight. Natilus hopes to balance speed with cost, shipping time-sensitive freight that isn’t valuable enough to fly, but is more valuable than much ...

Impact Of The COVID-19 Pandemic On Aviation
The COVID-19 pandemic has had a significant impact on the airline industry due to travel restrictions and a decimation in demand among travelers. Significant reductions in passenger numbers have resulted in flights being cancelled or planes flying empty between airports, which in turn massively reduced revenues for airlines and forced many airlines to lay off employees or declare bankruptcy. Some have attempted to avoid refunding cancelled trips to diminish their losses. Airliner manufacturers and airport operators have also laid off employees. Only several months into the pandemic, the crisis was already the worst in the aviation industry's history, according to statements made in early 2020 by Airbus' Guillaume Faury, EasyJet's Johan Lundgren, United Airlines' Oscar Munoz, Qantas' Alan Joyce, and media outlets: the ''Financial Times'', ''The New York Times'', and ''The Independent''. Flight cancellations Government regulations in Europe and the United States mandated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

737 MAX Groundings
The Boeing 737 MAX passenger airliner was grounded worldwide between March 2019 and December 2020longer in many jurisdictionsafter 346 people died in two crashes: Lion Air Flight 610 on October 29, 2018 and Ethiopian Airlines Flight 302 on March 10, 2019. The U.S. Federal Aviation Administration (FAA) resisted grounding the aircraft until March 13, 2019, when it received evidence of accident similarities. By then, 51 other regulators had already grounded the plane, and by March 18, 2019, all 387 aircraft in service were grounded. In 2016, FAA approved Boeing's request to remove references to a new Maneuvering Characteristics Augmentation System (MCAS) from the flight manual. In November 2018, after the Lion Air accident, Boeing instructed pilots to take corrective action in case of a malfunction, when the airplane would enter a series of automated nosedives. Boeing avoided revealing MCAS until pilots requested further explanation. In December 2018, the FAA privately predicted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Control
In electronics, a remote control (also known as a remote or clicker) is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other home appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside. Early television remote controls (1956–1977) used ultrasonic tones. Present-day remote controls are commonly consumer infrared devices which send digitally-coded pulses of infrared radiation. They control functions such as power, volume, channels, playback, track change, heat, fan speed, and vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
