Air-Cooled Condenser

　　Basically there are three types of airshipswhich are:RigidairshipsSemirigidNonRigidThefunctioning of all these type of airships vary from each other, whichare explained as below:Rigidairships:FrenchmanJoseph Spiess was the first person who gave the proposal of thesetypes of airships but his proposal failed to generate funding for itsactual development.Unlikerigid airships, partial framework was used in the making of semirigid airships, which contributed a lot in their success.” In1923, they were used for parasite fighter trials by the US army. However, later on Joseph Spiess succeeded inmaking these airships using the wooden framework, which took itsfirst flight in 1913. Itwas actually an extension to rigid airships and they were consideredas more reliable for military purpose. Theseairships were developed in high quantity in the end of 19thcentury. PL26, PL27, Zodiac V10, and Raab Katzenstein 27 were themost famous airships used in the 19thcentury. Zeppelin NT is the most famousairship from last few years.

These types of airships were first introduced inthe 1900s and were successfully employed due to their uniquefeatures. TC-3and Tc-7 were the most common non rigid airships used for thispurpose.Semirigid airshipsSemirigid airships were first used in the start of twentieth century.Rigidairships are the types of airships, which are not forced by pressurefor lifting gas within the envelope rather they are designed in sucha way that the envelope retains its shape using the internalstructure framework. In starting, controlling of anairship was considered as a difficult task but later on, manysophisticated airships were designed with power engines, which couldbe controlled easily.Nonrigid airshipsThesekinds of airships differ in their functioning from rigid andsemi-rigid airships.Nonrigid airships are also used for advertising purposes today. As time passed,improvements were made in these airships so that they can beeffectively managed and controlled. They invented the initial form of anairship that was actually a hot air balloon that was sent on theattitude of 6000 ft or 1800 m for its first flight. These airships were later on used in World WarI by different countries including France, United States, andGermany.Normally, corporate giants order these airships with their companyname, logo, and tag line to manufacturers (like Goodyear Company)which are then used for positioning in the minds of customers.Airshipswere first introduced in 1783 by two brothers named Jacques Etienneand Joseph Michel Montgolfier. P-791, G classblimps, K class blimps, M class blimps, and Water Cooled Condenser Manufacturers L class blimps are someexamples of non rigid airships. They are also referred to as “free flying aircraft.
