A descriptive look at the concept behind aircraft cabin pressurization

From the front it looks like any other corporate jet but viewed from behind you can see some serious engineering thought was given to this plane. The rear outside view reveals a luscious and curvaceous bird. But the biggest draw of the Global aircraft is its cabin, which is well, amazing. It is big, inviting and quite frankly makes me believe many passengers might not be so happy their trip has come to an end.

In In many respects, products today have been order to reduce time-to-market period, manufacturers need to fundamentally redesigned or physically inspired from shorten their design and development process.

It becomes vital that the design architecture solution is derived faster, existing predecessors in the market. This puts a higher which can be quite handful for complex products like an emphasis on physical aspects of product design in aircraft with the current geometrical-based approaches due constraining the development process.

The process needs to the plethora of physical alternatives to be considered. On to be worked around accommodating these physical the other hand, the search for design architecture solution constraints since the primary idea of redesigning is to not from the functional requirement is theoretically more effective since the functional space is smaller than physical make any unnecessary design changes [4].

Although this search space. This allows the design efforts to be more focused helps to ensure that the resultant product design will work and subsequently saves time, effort and resources.

With this to a certain extent, it certainly limits the designers in notion, there is a motivation to adapt the functional finding new, innovative solutions. In this paper, a sample case study of an aircraft functional analysis and the discussion on how this information is useful during the conceptual design stage are presented.

Example of different ways for lift generation.

For aircraft manufacturers, the twin business challenges today are to design and develop their aircraft with affordable cost and within much shorter timeframe [2]. In the complex product manufacturing like aircraft, improvement in design productivity will also govern the improvement of its industrial productivity [3].

Among others, this means that exploration of potential design solutions during the conceptual stage needs to be made more effective and faster, without sacrificing the design freedom to promote Figure 2.

Change of several conventional wing parameters. Plus, the aircraft design concept selection and development process needs to be supported with On the other hand, exploration of potential design reliable methods and tools that assist designers in avoiding solutions through the functional space is believed to be costly mistakes while fully exploring the design space for more flexible.

Indeed, physical descriptions of product design are supposed to be driven by its functions; hence the latter should become the constraint of the design process Manuscript received July 10, ; revised September 28, Moreover, the functional space is dependency between the subsystems, which means that all arguably more generic and therefore allows more flexible the related subsystems must co-exist in the design to conceptual building blocks when exploring all potential achieve that particular aircraft system level function.

In the design solutions. As depicted in Fig. However, if the designer readily has inter-linked together and their locations within the design conventional wing design as the final physical realization, are subjected to design compromises.

This paper intends to highlight system level, the aircraft level functions need to be broken the potential benefits that could be obtained by exploring down into their lower level functions.

The decomposition the conceptual design space through functional analysis. Aircraft functions are their functions. These subsystems level functions will build mainly derived from the corresponding requirements of the up the capability of the aircraft system to accomplish its four primary phases during its flight mission: In normal design process, the intended take-off, flight and post-landing operations.

According to performance of the aircraft will determine the required [5], more detailed sub-functions of these four high-level subsystems level functions.

For a weight-sensitive product tasks can be identified as shown in Fig. In this case, the like an aircraft, the required aircraft system level functions primary functions are decomposed into 12 sub-functions play an important role in selecting what subsystems should and it should be noted that to achieve some of the primary be incorporated into the design.

If any subsystem is functions, more than one sub-function might need to be unnecessarily installed, it will just needlessly increase the simultaneously executed. For instance, for a successful aircraft weight without contributing to its mission. Additionally, it must be manifestation is done in an optimized manner.

It could be observed that the 12 sub-functions are still too generic to be at the subsystems level.

This means that they can be further broken down into smaller or lower-level functions. The sustainment function refers to both scheduled and also unscheduled maintenance, whereby every aircraft is subjected to scheduled maintenance and servicing operations depending on the operating life of its parts and components.

In designing an aircraft, its adaptability to this pre-flight operation is often taken into Figure 3. Functional relationship between aircraft system and its account in order to save time and cost.The ball lightning traveled horizontally across the video frame at an average speed equivalent of m/s (28 ft/s).

It had a diameter of 5 m (16 ft) and covered a distance of about 15 m (49 ft) within those s. Plane Maker can display either the regular, “skinned” view of the aircraft model (where the model looks as it would in X-Plane), or it can display a wireframe view showing the actual structure of the aircraft.

The cabin altitude for comfort is low The is a commercial airliner that has a low cabin altitude of just 7, feet. What this means is that the cabin must be pressurized to 7, feet vs the Boeing ’s need to maintain 8, feet of cabin pressure.

Single-engine jet creates a new category of aircraft Single-engine jet creates a new category of aircraft May 24, By Thomas B Haines Call it what you want—The-Jet, the SJ50, the SF50, the Vision Jet—but the first single-engine general aviation jet is ready for prime time after a decade of development.

The Stinger's DMS includes five modes, accessible from a dial behind the shift lever, that change the driving characteristics by automatically adjusting how the engine, transmission, suspension, steering and AWD operate, while even altering the engine sound. Research by the US Air Force shows 80 per cent of pilots with no experience of decompression wait as long as 15 seconds to respond correctly to a loss of cabin pressure.

Because of the insidious effects of hypoxia on judgement and reasoning, the correct response to loss of cabin pressure is always to don the oxygen mask - immediately.
