R80 windows


















Vickers had applied for Permission to build a shed at Flookburgh, across the bay from their Barrow facility, on the shores of Morecambe Bay, a shed larger than their two existing sheds. They were originally granted Permission and allocated the steel needed. Work started on the Flookburgh site in March of , with some buildings commenced, and by July, some of the steel had arrived, and erection of the shed commenced.

Original designs for the shed were larger than anything that had been completed before, and with the idea that airship designs would get larger and bigger, to accommodate this plan, at some ft long and ft high, the proposed shed was much larger than their existing shed at Walney Island, and indeed the rigid sheds at Howden, Pulham and Cardington.

However with the pressures of war this was later cancelled, and plans refused due to a shortage of steel. This left Vickers with no option but to abandon the project for the Flookburgh shed, and also the contract to build the R37, which was then awarded to the Shorts Brothers Company and constructional facility at Cardington whom later commenced construction of the ship. With the limitations put upon them, and now no new shed available, Vickers asked the Admiralty for permission to build a ship of their own design.

Permission was granted by a busy Admiralty, to design a ship with the same dimensions of the existing dimensions of the existing R23 Class ship. The idea of a streamlined shape had originally been outlined in their earlier design of the HMA. Without the new larger shed, a smaller ship would have less disposable load compared to the other airship current Admiralty projects which were proposed and under construction in the UK. However it was agreed to continue with revised plans. The new design had been created in an outline in by the then Vickers chief designer, Barnes Wallis.

He was convinced that the Zahn shape of the earlier ships was wrong, and that the National Physical Laboratory had been mislead in their conclusions by the use of models that were too small to give consistently accurate results. The specification for a streamlined ship of some 1,, cubic feet was submitted on 14th November , and being approved on 21st November The Vickers design team of Barnes Wallis and H B Pratt set about designing a ship which would fit within the existing shed, which had been used to build the 23X class ships.

The R80 was designed to be a weapon of war, with an armament of three 2 pounder guns, rifled guns positioned on the top, and under the tail of the ship. Provision was also made for the ship to carry bomb racks, with the armament to be provided by the Admiralty.

Vickers produced an illustrated booklet which summarised their lighter than air activities during the hostilities. The description of the R80, then under construction was described as follows:.

In our R80 design we have embodied the results of our experiences and knowledge gained by the design of the R9 and R23 Classes, with the additional advantage of being able to include such details of the German ships as appeared to be of real value and superior to our own practice.

We have consequently produced in R80 a rigid airship of only 1,, cubic feet capacity that will give a performance in speed and endurance equal to that of the largest rigid airships built by the Germans of 2,, cubic feet capacity.

Our R37 having being transferred to Messrs Short Bros. Flookburgh shed and aerodrome being stopped, we were restricted to a size of airship that could be built in Walney shed. We therefore prepared designs for an airship of the largest possible size that could be built there, and embodied in this design all the best features obtained from the German 35 class and also the improvement suggested by our experience of the airships of R9 and R23 classes designed by us.

As we were given a free hand in the design without unnecessary restrictions as to strength, such as were imposed on us in 23 class vessels, we have produced a vessel which for it's size is considerably more efficient than any other Rigid Airship both in weight and general design.

An order for one ship to this design was placed with us in November and it is anticipated that this airship will be ready for trials in This airship has been designed entirely by Vickers Limited and was put in hand at the request of the British Admiralty with the objective of producing a rigid airship of 1,, cubic feet capacity that would give the same performance as a Navy Patrol Airship as the latest types of vessels of 2,, cubic feet capacity.

Exhausting research and a length series of experiments were carried out in connection with the design of Vickers' special light alloy "Duralumin" girders and other structural members for this ship, and with the information and results obtained, we were enabled to design the hull structure on a scientific basis to attain the utmost possible economy in weight, whilst giving the same strength as in the larger type of airships under all conditions of service.

A special study was also made of the design of all other features of the ship. Special Features of the design:. Hull - T he shape of the hull, which is based on the results of all of the best types of airships know, and also on a lengthy series of model experiments, is considered to be the most perfect known streamline shape, enabling the ship to attain it's speed with the least possible power.

In addition to the general improvement in the design of the hull structure referred to above, many detailed improvements have been introduced in the design of the girders, joints and the system of wiring. The hull is provided with bow mooring attachments on the Vickers Patent Principle which enables the ship to be moored out from a mooring tower in such a manner that it is free to turn in any direction and lie with the wind, thus permitting the vessel to be moored out safely under the most severe weather conditions.

GASBAGS- The gasbags in the airship are made under a new system, patented by Vickers Limited, which enables them to be constructed of the lightest possible weight whilst at the same time giving extremely good gas holding properties. CARS - Four cars are attached to the hull viz:. Forward Control Car and Machinery Car, which are flexibly connected together to form one streamlined body. Two wing cars for machinery only, attached on opposite sides of the airship. The Control Car is of sufficient size to contain all the navigating controls and instruments and the navigating crew, with provision to give sufficient room and convenience for their comfort.

The wireless system is also fitted in this car. Forward Machinery Car carries two engines arranged en echelon driving directly one propeller at the after end. The driving gear is also arranged as to enable the propeller to be driven by either one or both of the engines.

For example, if a protection is inactive because of its Performance rating, it is not enabled even if its category is in Protections to activate. There are numerous protections available in IPS.

It takes time to become familiar with those that are relevant to your environment. Some are easily configured for basic security and can be safely activated automatically. In the Threat Prevention profile, you can configure an updates policy for IPS protections that were newly updated.

Active - According to profile settings -Selected by default. Protections are activated according to the settings in the General page of the Profile. This is the Check Point recommended configuration. Set activation as staging mode - Newly updated protections remain in staging mode until you change their configuration.

The default action for protections in staging mode is Detect. You can change the action manually in the IPS Protections page. Level Message 2 of 5. Good luck. Was this reply helpful?
