The so-called helipad refers to the civil aviation, military aviation and other relevant departments issued by the technical and construction standards, by the qualified units designed, manufactured and constructed for helicopter all-weather landing and takeoff for civil aviation transportation, navigation operations and military flight aviation infrastructure.
In the country's efforts to promote the development of general aviation industry today, the helipad construction such as spring in the ascendant, and all kinds of problems are also bred in it. Helipad as a little-known mechanical and electrical products or special infrastructure projects, whether it is a medical and health institutions or relevant enterprises and institutions, almost all faced with the need to build but do not know how to choose the **** the same problem.
Because of the demand side of the cognitive bias, the supply side of the mixed, coupled with asymmetric information, making this market has a more general supply and demand imbalance phenomenon. How to choose to build the ideal helipad is more and more users and potential users are concerned about the concern of a hot topic, this paper discusses this issue, for your reference in practice.
One, the principle of safety first
As we all know, including aeromedical services, general aviation flights are typically recognized as high-risk operations, to ensure safety is the first priority of the operation of the flight and the most important. Therefore, how to ensure safety has become the eternal topic of human flight and never-ending pursuit.
No doubt, whether fixed-wing aircraft or rotorcraft, in the takeoff and landing phase of the risk factors are relatively more large, helicopters as the important and the main type of aviation and aeromedical operations, and takeoff and landing safety related to the apron undoubtedly become the focus of attention and the core.
So, choose to build the helipad first to grasp the "safety first" basic principle, from planning, site selection, design, manufacturing, field, construction, installation, testing, calibration, use, maintenance, management and other aspects of the safety considerations in the first place, and strive to be foolproof. In order to achieve or ensure foolproof, but also grasp a series of certification or evaluation principles.
Second, the principle of systematic and comprehensive
Compared with other aircraft, helicopters vertical take-off and landing, hovering in the air and inverted side flight of the unique performance and superiority of the unparalleled, so that it is very suitable for the development of aviation emergency rescue and aeromedical ambulance operation is to solve the obstacles to the passage of the land and the last 10 kilometers of the only effective and efficient means.
In order to give full play to the inherent advantages of helicopters and to meet the actual needs of all-weather operation flights, it is necessary to build not only a helipad, but a helipad system. The former can usually only be used for daytime takeoff and landing, while the latter is often able to be used for day and night takeoff and landing, in addition to apron panels and basic support, should also include wind vane, guide marking, navigational aids, lighting, wireless communications, satellite positioning, lightning, de-icing and snow melting, fire fighting, tethered to the stationary, fuel supply, centralized control, and other sub-systems or subsystems, to ensure that the meteorological conditions allow for takeoff and landing at any time, irrespective of the day and night, so that rapid response, timely arrival, and the ability to meet the needs of the helicopters. Thus realizing rapid response, timely arrival, so that rescue and relief or saving lives and injuries in the seconds, seconds to fight in a fruitful manner, fully embodies the "time is life", "saving lives as fire" practice philosophy.
Third, the principle of advanced and practical
In terms of system integration, helipad, in addition to the main structure of the apron panels, foundation support and the board surface sprayed with the calibration of the guide signs, from the point of view of belonging to the subsystems or sub-systems and sub-systems to use the safety considerations, but also deserve to grasp the advanced and practical this two are indispensable, equally important principle of accreditation: "" advanced" undoubtedly refers to the apron panel, foundation support and board surface spraying of the calibration guide signs. Advanced" undoubtedly refers to the unprecedented or top, with the implication of invention and innovation.
In other words, if the helipad is such a high technological content of the intellectual/manufacturing products often with or accompanied by a certain amount of invention patents and has completely independent intellectual property rights; and "practical" is largely referred to as a good or handy, targeted, appropriate or moderately ahead of corresponding to the helipad Apron refers to adapt to and meet the classification of stereotypes landing, according to which the two must complement each other, complement each other, organic combination, the pearl, thus reflecting the scientific and reasonable, the best performance of the construction concept.
Four, the principle of durability
Helicopters in the take-off and landing, especially when landing, due to the self-weight and load and the fall of a variety of different forces generated by the collection of impact in the wheels or skids touching the apron panels of the apron is bound to have a certain amount of damage in the moment, over time, day after day, on the apron's life and use of the life of the apron to obviously cause a corresponding impact.
This impact with the design structure, building materials, construction quality, environmental conditions, use and maintenance factors are related, especially the design structure and components of the material has great relevance. At present, whether it is the design life or service life, the design of scientific, structurally sound, unique materials, exquisite craftsmanship of the all-aluminum multi-layer helipad is able to use the longest apron, according to the developer of the simulation experiment report data show that it can be free of maintenance in 50 years, durable. Not only that, because of its columnar square holes and sawtooth structure has the function of noise and vibration damping, but also can reduce the landing gear and even the fuselage of the force, and then also prolonged the service life of the force components, cost-effective, cost-effective, win-win situation, a multi-purpose.
Fifth, the principle of comprehensive benefits
Inexpensive and value for money have a specific or corresponding significance, the question is how to understand and how to compare, which is very important to grasp the overall interests and the principle of comprehensive benefits.
The so-called overall interest refers to the aviation medical rescue, taking into account other aviation emergency rescue needs, including rescue and relief, public security and firefighting, counter-terrorism and even official flights, in order to realize a ping multi-purpose, improve the efficiency of use, and give play to the benefits of the investment; comprehensive benefit refers to the need to clear the economic accounts, but also to calculate the safety accounts, social accounts, political accounts and impact accounts, etc., to be able to count, counting, counting the total account, weighing the advantages and disadvantages. Calculate the total account, weigh the pros and cons, grasp the principle, rational thinking, scientific trade-offs, in the helipad such a matter of safety on the construction of special projects is best to one step, once and for all.
In order to safety or ensure safety, spend in more money is also worthwhile, both to be inexpensive, but also value for money, should not spend a penny to not spend, can be spent can not be spent to spend the money to be cautious to spend less money, careful budgeting; and the money should be spent a penny and do not save the good steel on the knife edge to give full play to the efficiency of the investment, so that the benefits of the investment to be maximized.
Sixth, the pursuit of excellence in principle
There is "not afraid of not knowing the goods, afraid of comparing the goods", the difference and the gap refers to the same things under the same conditions as the results of the comparison of the formation of the results and conclusions. The principle of the pursuit of excellence refers to the apron construction to keep pace with the times, beyond the self, excellence, the pursuit of perfection.
Currently the domestic helipad construction, although similar, but based on the construction concept, engineering design, apron structure, construction materials, manufacturing processes, system integration of different and considerable differences, thus bringing different visual, tactile, feeling different, application, effect, different benefits of different feelings and consequences.
The all-aluminum multi-layer helipad with the advantage of latecomer is the model of difference, unprecedented, is the innovative boutique of standardization, standardization and modernization, applicable to any environment and any type of helipad construction, especially the roof-type apron, which is undoubtedly the most ideal product. Due to the all-aluminum multi-layer lightweight and durable, light weight, high strength, good toughness, not only for roof-type, platform-type, elevated type and other types of apron, even if the ground-type helipad is best to lay all-aluminum multi-layer structure on the surface, so that the pursuit of excellence in the pursuit of high-quality products and high-quality engineering.
In summary, the selection of the ideal helipad must be grasped on the basis of the above principles of comprehensive consideration. It is said that facts speak louder than words, helicopters in the system apron landing and takeoff passengers feel and the pilot's evaluation is the best certification. The all-aluminum multi-layer helipad developed and produced by Zhejiang Shengxiang Aviation Science and Technology Co., Ltd (the apron is simply called "all-aluminum", but in fact it contains a high ratio of confidential trace elements) has been proved to be the most advanced, practical and useful helipad at present, and the comprehensive advantages of its scientific design and structure, unique construction materials and perfect system integration will be realized by practice and time. The comprehensive advantages formed by its scientific design and structure, unique construction materials and perfect system integration will be continuously verified by practice and time. It is undoubtedly a scientific, wise, practical and best choice for any user to take it as the first choice, which lays a solid foundation for safe take-off and landing and operation flight.
The all-aluminum multi-story helipad is currently the most advanced helipad in the world, and the panoramic view of this apron is pleasing to the eye. The picture shows the ground-type all-aluminum multilayer helipad built at the PLA 153rd Central Hospital from the air, and the wide white band on the right side, which is connected to the helipad, is a stretcher truck ramp.
Tongji University Affiliated Dongfang Hospital (Shanghai Dongfang Hospital) is located in the high-rise Lujiazui area of Pudong, which has a lot of land, so it can only build a rooftop apron to carry out aeromedical operations, and the picture shows an all-aluminum multilevel helipad on the top of the hospital's new ward building.
Aeromedical service is an all-weather operation. The picture shows a helicopter landing in the night at Zhuji City People's Hospital in Zhejiang Province, marking the apron has the conditions for day and night takeoff and landing, laying the foundation for timely rescue and treatment of the wounded.
The ground-based, all-aluminum, multi-story helipad system built by the People's Hospital of Shifang City, Sichuan Province, looks dazzling under the moonlight.
The picture shows the surface of the all-aluminum multilayer helipad with columnar square holes and sawtooth structure with sound damping and vibration damping function, which makes the contact force, force conduction, and impact and bearing force more balanced and reasonable, and not only makes the apron durable, but also prolongs the life of the landing gear accordingly.
All-aluminum multi-layer helipad panel under the red pipe and storage tank is the pressure type foam fire extinguishing sub-system, the system depending on the different fire conditions can be instantaneous spray foam or water.
The all-aluminum multideck helipad system has navigation lights and firefighting subsystems that are turned on at night.
Compared to the all-aluminum multilayer helipad, other materials and structures look bland.
Compared to the automatic firefighting facilities of the all-aluminum multilayer helipad system, the apron built by a provincial people's hospital relies on this manually operated firefighting device response time and firefighting effect can be imagined.
