During the Chinese New Year in 2016, a movie "Mermaid", which was personally directed by Master Xing, was hotly released. This movie conveys the concept of environmental protection in a humorous and hilarious way that people and animals live in harmony, and is enjoyed by many moviegoers, and has become one of the few good and popular films of the year. But the most impressive scene in "Mermaid" is Zheng's dazzling appearance. The film starts with a weirdly dressed, thinning hair real estate agent Zheng attending Liu Xuan (Deng Chao) banquet is carrying a jetpack from the sky, and this high-tech artifact is also known as the highlight of the whole film, and later the main character Liu Xuan is also carrying this flying machine to fly over the congested road instantly save the mermaid.
I was thinking: if you can have such a flying machine, from then on, you may be able to say goodbye to the rush hour crowded bus and subway, traffic jam bad days. But don't believe me, there is really a British company called Martin Aircraft has created this kind of flying machine, and claimed that the world's only real flying backpack. The plane's fuselage is said to be made of 3D printed titanium parts, followed by its use of two key "blowing" technologies that can replace moving surfaces such as flaps and ailerons. Unlike most flying backpacks that use rockets and water vapor jets to power them, Martin Aircraft has introduced a product that uses jet vortices to achieve vertical takeoff and landing. It can fly at 100 mph, can fly at an altitude of over 13,048 meters, and has a current endurance of 10 minutes.
In addition to providing sufficient power, this flight backpack is also unique in design, small and lightweight, and can be placed in the trunk of a car.
The jetpack may be acceptable to most people, because there is a precedent for water jetpacks and other sea excursions, but the flight distance of the backpack makes people feel like a joke. But if the plane also "spray" into the sky, what do you think? Just last Thursday, the world's first flapless aircraft was "sprayed" into the sky for its first flight in northwest Wales.
The aircraft, a collaboration between British defense giant BAE and researchers from the University of Manchester, is a breath of fresh air from head to toe, inside and out. Firstly the aircraft's fuselage is made from 3D printed titanium parts, and secondly it uses two key 'blow-up' technologies that can replace moving surfaces such as flaps and ailerons.
Flaps and ailerons are important components on an aircraft's wings. There are two wings on an aircraft, each with a flap and aileron on top. The one near the fuselage is the flap and the one away from the fuselage is the aileron. Simply put, the flaps govern the takeoff and landing of the aircraft and the ailerons govern the turning of the aircraft. Two technologies that could revolutionize the future of aircraft design are the "blow-by" alternatives to flaps and ailerons, which could improve the performance and control of the aircraft. The first is wing cyclic control. In this case, air from the aircraft's engines is exhausted and "ejected" supersonically through narrow slots around the trailing edge of the specially shaped wing to do the same job as the ailerons. The second is jet thrust vectoring. This involves deflecting the jet exhaust of the engine by blowing air inside the nozzle to change the pitch of the aircraft.
Today, conventional aircraft rely on flaps, ailerons, elevators, rudders, etc. for more complex flights. Despite more than a century of development, it is a very crude system that is inefficient and relies on complex, expensive, heavy-duty mechanical components to work. replacing moving surfaces with blown air technology could lead to the development of lighter, more reliable, cheaper and better performing aircraft, which paves the way for future aircraft designs, BAE Systems said.
Moreover, these technologies could also improve aircraft stealth by reducing the gaps and edges that currently make aircraft easily visible on radar, and thus will also be used in the development of future combat air systems. Such aircraft would also be fundamentally different from current jet aircraft. The jet engine used in the current jet aircraft relies on the recoil of the backward high-speed jet of gas produced during fuel combustion to make the aircraft fly forward, and it allows the aircraft to gain more thrust and fly faster.
But in fact, this project has taken a long time to accumulate and test the cutting-edge technology in the early stages. And this technology has not really mature, such as the current only for single-engine aircraft, etc., can not be directly used in manned aircraft.
