Something like this as in TP de Paravicini patent

The wing inlets that TP de Paravicini showed in several Patents was not executed because the wing designers did not want to redesign the structure to accommodate the flow. Hence the underbelly or chin cowled chamber. the Math was well understood by TP de P because Rolls Royce valued his...

Original patent Patent filed 1936 by TP de Paravicini. Mustang is similar but later. So used this basic patent.

His name was indeed Thomas Pitt de Paravicini. But for patents the name filed is just TP de Paravicini. Another pic from another patent

Bottlehead reply, Meridith is with a capital M please, You are being very disingenuous about patents. and theory, Tom de Paravicini had done all the theory as he was the best mathematician at Rolls Royce at the time and also became the youngest to become a member of the Royal Aeronautical...

Technical Data Digest The net has lost a lot of text. So continuing. Here is a list of GB patents by Ellor and de Paravicini. GB463303, GB471371, GB472334, GB472555, GB472820, GB473340, GB473341, GB484300 Then one of his patents on exhaust ejectors GB471177. All of these relate to cooling...

Bottlehead replies. There are numerous patents that TP de Paravicini alone or with his boss at Rolls Royce Edwin Ellor filed that covered various methods of cooling by means of utilizing waste heat. TP de Paravicini was at Farnborough research prior to being recruited to Rolls Royce. It...

I wish people would read the various GB patents held by TP de Paravicini. He covered the negative drag in various patents including air cooled radial engines. Of course final designs needed to go through a few iterations to get optimum performance. The first paper was in 1932. He was at...

Merely that History gets edited and sometimes the rightful attributes get rubbed out. Hence trying to get credit where it is due. Studying the patents gives you an insight as to how negative drag works and how aircraft adapted the methods. Some of his papers are in the Royal institution and I...

Yes. It was TO de Paravicini who rightfully should be credit with negative drag. As he was at the Farnborough Aircraft establishment when he write the original paper. Metedith was a fellow engineer. But de Paravicini had the better math skills to prove it. There are several patents in his name...

See patent GB472555,& GB472334A

I think you have to look at the patents covered by TP de Paravicini under GB entries. He covered aircintake on wing edges as well as the chin and or underbelly housing. All were in the 1936-8 period. He covered air cooled as well as liquid cooled engines.

I must add correction, Should have been TP de Paravicini and Wolfhound and Stewart Tresillan.

I am new to this forum as I am not an aeronautical engineer, However my Uncle Thomas Pitt de Paravicini worked in the 30's after leaving university at the Aircraft Establishment at Farborough and was with Meredith before going to Rolls Royce Derby and had most of the patents on what he called...
