The link is died,how to get it again ?.
There is no easy way to get back there. For some reason, Google Patents changed all of its urls since you posted that image (reinforcing the need to provide patent numbers and application titles - not just ever-changable urls).
So, go to Google Patents and search: bell+aircraft+corporation+aircraft "1943".
Around the date of your image, a slew of Design Patent applications were submitted on behalf of the Bell Aircraft Corporation. Reading the description sections of such Design Patent applications, you will see phrases such an "ornamental design for an airplane". In other words, the external appearance or layout is being claimed to be original ... so not a 'design' in the way we used that word.
To know precisely what you're looking at, you must read the summary information for details. But, even then, Google Patents can present plenty of false leads. One pitfall is the use of the word "attorney".
For example, US Design Patent 136,580 (USD 136580S) was submitted for the Model 32 (later XP-77) with Robert J. Woods listed as "inventor". In the description, Woods refers specifically to "my new design". And, of course, we know Bob Woods to have been Bell Aircraft's chief engineer. But the descriptions are rarely that categorical.
Google Patents cannot seem to distinguish between "attorney" and "inventor". For example, Google Patents lists "Inventor Herbert L. Bowers" for Des.146,072 (titled the "Bowers airplane") which covers the Design Patent for Bell's D-16/Model 40 (later XP-83). Herbert L. Bowers is given as another "attorney". But, actually, Herbert Bowers was an aeronautical engineer and had been Bob Woods' assistant. Alas, Woods is not usually the engineer attributed with the design of the D-16/Model 40.
Closer in time to your image was Des. 143,758 (USD143758S) listing a "RHODES AIRPLANE" - which looks like a very early stab at a jet-powered
Kingcobra. The "inventor" section is garbled. In the text, this is given as "attorney" E.P. Rhodes (who, in reality, would later become project engineer on the Model 40). BTW, to further confuse matters, many sources list 'Charles' Rhodes as the designer of the XP-83. In its summary, Google Patents lists "Inventor Greiner Road". This bit of Google AI-generated nonsense comes from the garbling of Edgar Rhodes' Clarence, NY, home address at the time.
The take-home here is read Google Patents descriptions very carefully and approach any Google summaries with scepticism.
