Pretty Good Privacy and Snuko in the Aerospace Industry

April 5th, 2021

Aerospace has now developed a sophisticated approach to ensure confidentiality of data. This is primarily because of its association with the military. The data confidentiality is maintained not only in its dealings with the military and defense sectors but also with its other business associates.

The requirements of confidentiality are, however, complex. For example, some are monitored by national regulations and demand the use of the encryption algorithms mandated by their national security agency. On the other hand, there are some that require those products that have been reviewed and approved by the agency or they incorporate certain devices.

The OpenPGP standard is now being used for giving a substantial level of resistance to attack for quite some time. Also, there have been specific implementations and approval of some products that use algorithms within those supported by this Pretty Good Privacy (PGP) standard.

The aerospace industry was the very first user of security systems. Therefore, as a good anti-theft and data protection measure, they have heavily invested in OpenPGP and PGP solutions. One major reason for this could be the fact that, for a long time, these were the only solutions available.

Although the information networks are locked down and secured in this industry, the systems themselves are sometimes left vulnerable. Since all the sensitive information is stored in the computers and laptops, securing these elements becomes a priority. With the network locked down, it will become difficult for a hacker to penetrate into systems through another terminal. But, the system can also be hacked into individually. Also, with laptop theft on the rise, the confidential data can easily find its way to unauthorized users.

To prevent this kind of loss, there are many tools available. These software options lock down the system the minute it has been reported lost. Also, they can help you identify where your computer is located within 10 to 20 meters. They also take regular pictures of the one using the computer and also snapshots of the screen to tell you what an unauthentic user was doing with your system. One such software adept with all these features and much more is Snuko.

The use of software tools is important for the aerospace industry. Since all the information they deal with is confidential, it becomes increasingly important for them to take all precautions possible to protect it. Therefore, along with OpenPGP, the use of anti-theft software options should also be encouraged.

Facts You Need to Know About Fireplaces and Bellows

March 5th, 2021

There are two main types of bellows such as formed bellows and welded bellows. Welded metal bellows find it’s use in varied forms in different industries. Bellows are manufactured with systematic planning, product design, maintaining quality standards coupled with finite element and metallurgical analysis besides functional test and thermal tests. These welded metal bellows perform under stressful environment such as high pressure and extreme temperature. This characteristic helps metal bellows to act as temperature transducer.

Uses of metal bellows

Metal bellows and bellows valve have wide range of applications and benefits. First of, they are corrosion resistant, heat and pressure resistant, they enhance product longevity, ensure cleanliness at the work place, offers much sought flexibility, come with better sealing performance and last they are compatible to extreme environment conditions including salt spray, high humidity as well as corrosive fluids.

Different types of bellows and bellow products

Some of the bellow products include accumulators, surge arrestors, reservoirs which are used in fluid management technologies. These welded bellows differ in function but still come with similar construction.

Each of these bellow components consist of an outer containment, internal bellows separator and ports either in one side or in both sides depending upon application. The bellows act as separator that is welded on one end of the containment. The other end of the bellow is closed and it slides through containment as the bellows contracts and expands with the fluid system. Depending upon the need and the application, the fluid can be either inside the bellows or even outside like between the bellows and the containment

Some welded bellows act as temperature sensors, pressure sensors, aneroid sensors and also transducers such as military temperature transducer and aerospace temperature transducer. Depending upon application, the metal bellows are used and they can function as valve seals, vibration dampeners and pressure and temperature sensors. In case of pressure transducers two small bellows are generally joined with a capillary tube.

The gas-filled bellows are used in air density controls, fuel controls and in pressure chamber. It is the liquid filled bellows that find wide application in the field of transducers such as temperature-motion transducer, temperature-force transducer, motion-motion transducer and many more.

These transducers act to transform one form of energy into another and it is the welded metal bellows that actually aid in the altitude sensing system, cockpit cooling system and thermal control for optical application system.

Bellows and related products find their usage in industries such as aerospace, oil, gas and chemical, military and defense, electrical transmission and distribution and devices in research and scientific laboratories besides finding wide industrial applications.
