Answer to Critics of Inflatable and Expandable Fighter Aircraft Wings
Different nations are developing advanced fighter aircrafts that have beaten all odds. Well, US used to be the benchmark when it came to jet fighters.

Some aerospace designers believe that Mr. Lance Winslow's design and style modification of current day fighter aircraft and UAVs to incorporate an inflatable and expandable wing isn't feasible or desirable. There critique incorporates lots of points, 3 of these points are worthy of addressing, when the rest of their debate and critique are irrelevant and in reality show their lack of understanding of Mr. Lance Winslow's great notion.
These critics believe that inflatable expandable wings will:
1.) Have to have for Larger cavity for wing whilst retracted.
2.) Be like other models of aircraft with retracting wings, which did not perform.
3.) Have a loss of use of fuselage cavity for other elements and fuel
In addressing the design critique in these things we'll show that they key components to be related with our notion:
It's my contention that the wing when not in use would be deflated and take up little space and fit in to the finish cap, which would resemble a stub sticking out with the fuselage. The stub would also serve as the top edge and spar when expanded and have the similar camber as an end cap since it would when acting as the top edge. In essence taking up no additional space in the fuselage location such as other models including the "Roll-Wing" notion. The roll wing idea an additional try at a related design, which was utilized as an example by the gentleman of, which attempted precisely the same goals.
We believe that as our notion would have an inflatable wing within the end cap, that we would not be related sufficient for the roll-wing concept to make a fair comparison and additional agree that the roll wing concept is interesting but also have to have perform. Indeed we think in addition towards the roll-wing concept needing added perform that it is not aesthetically appropriate and would in all probability not be economically viable in the market place spot as its design and style can be a radical departure from what a lot of people assume an aircraft should appear like. As a point on this we think that the JSF was awarded to Lockheed as an alternative to Boeing for partly this reason, the Lockheed version was sexier. Even when the Lockheed style nonetheless has structural problems using the availability and costs with the titanium bulk head and also the Boeing version appeared to possess exceptional performance. There had been we think some Air Force larger ups that didn't like its looks.
Retracting an entire wing in to the fuselage does take up a lot of space and as a result the gentleman tends to make a superb point around the require for other components inside the fuselage for example the engine, landing gear, fuel tanks which would mean enlarging the fuselage for the point of defeating the objective of retracting the wings. Nevertheless in our notion the wing folds nicely like an accordion when retracted for high-speed flight.
The gentleman further indicated that there is certainly enhanced weight in such ideas as retractable wings including the motors to move the wings. We agree that their might be some additional weight for our inflatable expandable wings due to the components for example motors and compression canisters, nonetheless due to the fact our wing will be inflatable it is going to be ultra light weight to begin with, creating up for substantially on the distinction. The leading edge/wing spar folding out element will likely be full strength and support substantially with the wing loading. The JSF features a wing loading of 91.four lb/ft. The existing material we envision for our expandable wing is utilized in inflatable water dams for rivers and lakes and can quickly withstand a greater wing loading.
The motor to move the wing spar only won't be substantial like the F-14. The motor is not going to be used before take off and can not be deployed against the relative wind at more than 450 Knots.
The gentleman also had indicated that given that the wing is definitely an inflatable version it would not be capable of retailer fuel. Fuel storage inside the wings of fighter aircraft is typical, but not all have fuel storage in the wings. This can be a fantastic point and hence this will have to be addressed with bigger fuel tanks inside the fuselage. Nevertheless it need to also be noted that we'll be saving weight wing our wing, that will enhance functionality and in cruise we will be employing far much less fuel by substantially decreasing the drag. In addition it ought to be noted that the JSF includes a variety of only 650 Nautical Miles with no drop tanks, so we think we are within the ballpark to match with our additional effective design. The truth is it is actually feasible that a slightly modified JSF indeed could be an interesting platform to attempt test this new concept. Consider again we want greater objections from these who contact themselves worldclass aerospace designers.
