Today, the whole country is vigorously promoting the great development of the general aviation industry, and the construction of helipads is mushrooming, and various problems are gestating in it. As a little-known electromechanical product or special infrastructure project, the helipad faces almost the same problem that needs to be built but does not know how to choose.
Due to the misunderstanding of the demand side and the asymmetry of information between the mixed supply side and the mixed supply side, there is a general imbalance between supply and demand in this market. How to choose an ideal helipad is a hot topic of concern to more and more users and potential users. This paper discusses this issue for your reference in practice.
First, the principle of safety first
As we all know, general aviation flight, including aviation medical service, is a typical and recognized high-risk operation, and ensuring safety is the primary task of flight operation. Therefore, how to ensure safety has become an eternal topic and endless pursuit of human flight.
Undoubtedly, both fixed-wing aircraft and rotary-wing aircraft have relatively more risk factors in the process of take-off and landing. As an important and main model for navigation and aviation medical operations, the apron related to take-off and landing safety has undoubtedly become the focus and core of much attention.
Therefore, when choosing to build a helipad, we must first grasp the basic principle of "safety first", and put safety considerations in the first place from all aspects such as planning, site selection, design, manufacturing, approach, construction, installation, testing, calibration, use, maintenance and management, so as to be foolproof. In order to achieve or ensure foolproof, we must master a series of certification or evaluation principles.
Second, the principle of systematicness and comprehensiveness.
Compared with other aircraft, the unique performance and superiority of helicopter in vertical take-off and landing, hovering in the air and flying sideways are unparalleled, which makes it very suitable for aviation emergency rescue and aviation medical rescue, and is the only effective and fast means to solve land traffic obstacles and finally 10 km.
In order to give full play to the inherent advantages of helicopters and meet the actual needs of all-weather flight, it is necessary to build not only helipad, but also helipad system. The former can usually only be used for taking off and landing during the day, while the latter can often be used for taking off during the day and at night. Besides apron panel and foundation support, it should also include subsystems or subsystems such as wind vane, guide sign, navigation aid light, wireless communication, satellite positioning, lightning protection, deicing and snow melting, fire fighting, mooring, oil supply and water replenishment, and centralized control. In order to ensure that the weather conditions permit, take off and land at any time day and night, achieve rapid response, arrive in time, and do a good job in emergency rescue and disaster relief.
Three. Advanced and practical principles
As far as system integration is concerned, in addition to the calibration and guiding signs of the main structure of helipad, namely apron panel, foundation support and panel spraying, from the perspective of the safety of its subordinate or affiliated subsystems and subsystems, we should also grasp the two indispensable and equally important certification principles of advanced nature and practicality: "advanced nature" undoubtedly means unprecedented or among the best, and has the meaning of invention and innovation.
In other words, if it is a high-tech intellectual/manufacturing product like helipad, it often owns or comes with a certain amount of invention patents and completely independent intellectual property rights; To a large extent, "practical" means easy to use or handy, targeted, just right or moderately advanced, corresponding to the helipad, especially to adapt to and meet the take-off and landing of classified aircraft. Accordingly, the two must complement each other, complement each other, organically combine, form a perfect combination, and embody the scientific and reasonable construction concept with the best efficiency.
Fourth, the principle of durability
When a helicopter takes off and lands, especially when landing, the impact of various forces caused by its own weight, load and descent will inevitably damage the apron at the moment when the wheel or sled touches the apron panel. Over time, it will obviously have a corresponding impact on the life and service life of aprons.
This influence is related to the design structure, construction materials, construction quality, environmental conditions, use and maintenance, especially the design structure and component materials. At present, the all-aluminum multi-layer helipad with scientific design, reasonable structure, unique materials and exquisite technology has the longest service life, regardless of its design life or service life. According to the data of the developer's simulation experiment report, it can be maintenance-free and durable within 50 years. Not only that, because its columnar square hole and serrated structure have the functions of silencing, noise reduction and damping, it can also reduce the stress on the landing gear and even the fuselage, thus prolonging the service life of the stressed parts, with high cost performance ratio, high cost-effectiveness ratio and mutual benefit.
Verb (abbreviation of verb) principle of comprehensive benefit
Good quality and low price have specific or corresponding meanings. The problem is how to understand and compare them, and it is very important to grasp the principle of overall interests and comprehensive benefits.
The so-called overall interest refers to giving priority to aviation medical rescue, taking into account other aviation emergency rescue needs, including emergency rescue and disaster relief, public security fire fighting, anti-terrorism and even official flights, realizing multi-purpose of one apron, improving the use efficiency and giving play to investment benefits; Comprehensive benefit refers to not only economic accounts, but also security accounts, social accounts, political accounts, impact accounts and so on. It is best to calculate an account, a big account, a general ledger, weigh the pros and cons, grasp the principles, think rationally and choose scientifically. In the construction of special projects involving safety, such as helipad, it is best to put them in place at one time.
For the sake of safety or ensuring safety, it is worthwhile to spend a lot of money. It should be cheap and good, and it is worth the money. Don't spend money you shouldn't spend, spend less and be careful. And don't save a penny of money, use good steel in the cutting edge, give full play to the investment benefit, and maximize the investment benefit.
Sixth, the principle of pursuing Excellence
There is a saying that "if you don't know the goods, you are afraid to shop around." Differences and gaps refer to the results and conclusions formed by comparing the same things under the same conditions. The principle of pursuing Excellence is that apron construction should keep pace with the times, surpass itself, strive for perfection and pursue perfection.
At present, although the construction of helipad in China is similar, there are considerable differences based on the differences in construction concept, engineering design, apron structure, building materials, manufacturing technology and system integration, which bring different feelings and consequences such as vision, touch, feeling, application, effect and benefit.
The all-aluminum multi-layer helipad with the advantage of backwardness is a unique model, unprecedented, standardized and modern innovative products, suitable for any environment, any type of helipad construction, especially the roof helipad, which is undoubtedly the most ideal product. All-aluminum multilayer is light and durable, light in weight, high in strength and good in toughness. It is not only suitable for various types of aprons, such as roof, platform and elevated apron, but also it is best to lay all-aluminum multi-layer structure on the surface of ground helipad, so as to make it a high-quality product and excellent project that pursues Excellence.
To sum up, choosing an ideal helipad must be considered comprehensively on the basis of grasping the above principles. There is a saying that facts speak louder than words, and passengers' feelings and pilots' comments when helicopters take off and land on the standard apron are the best certification. The all-aluminum multi-layer helipad developed and produced by Zhejiang Sheng Xiang Aviation Technology Co., Ltd. (although the helipad is abbreviated as "all-aluminum" and actually contains trace elements with high confidentiality rate) has been proved to be an advanced, practical and easy-to-use helipad, and its comprehensive advantages formed by scientific design structure, unique construction materials and perfect system integration will be continuously verified by practice and time. For any user, taking it as the first choice is undoubtedly a scientific, wise and pragmatic best choice, which has laid a solid foundation for safe take-off and landing and operational flight.
The all-aluminum multi-layer helipad is the most advanced helipad in the world at present, and the panoramic view of this helipad is pleasing to the eye. The picture shows the ground-type all-aluminum multi-layer helipad built by PLA 153 Central Hospital, which was photographed from the air. The white broadband connected to the helipad on the right is the stretcher ramp.
The Oriental Hospital affiliated to Tongji University (Shanghai Oriental Hospital) is headquartered in Lujiazui, Pudong, where there are many tall buildings. Only the rooftop apron can be used for aviation medical operations. The picture shows the all-aluminum multi-storey helipad built on the top floor of the new ward building of the hospital.
Aviation medical services are operated around the clock. The picture shows the experimental helicopter landing slowly in Zhuji People's Hospital of Zhejiang Province in the dark, which indicates that the apron has the conditions for taking off and landing day and night, laying the foundation for saving lives in time.
