Vengenza: no internal bombay. This is designed to be a big gun plane, with the possibility of the guns being deleted and a large, jettisionable belly rocket pod mounted later should rocket accuracy improve enough later in the war to replace guns.
I intend...alas, I cannot give you a time frame....but I intend, as another member of this forum told me in a PM, to buy and learn to use the X-plane software, and then to design all three of these planes and then post the results here. Then you can not only see them but fly them!
Vraciu: THIS is the reason why I started this thread! I want to see some really imaginative solutions. Here are some thoughts I had to make an alternate B-29. Feel free to make use of them!
(1) We know that if there had been enough research money available, the Rolls Royce Griffon, a 2,000 hp class narrow frontal area engine, could have been available in numbers with the bugs worked out in 1943. Let's start your bomber on the premise that Rolls Royce sold the rights to the US Gov in 1941 and the USG promptly gave the patents and drawings to Continental Allision etc and told them to push the design and guaranteed them a contract. By 1943 a stable 2050 hp design is ready.
(2) Now with that 2050 hp design you throw in a new twist: central supercharging, as I used in the BB 129. Only this central is not for protection purposes, but for increasing the power of the engines which will be embedded in the wings, like the B-36. Since each of the wing engines will no longer have the duty of powering the supercharger we should get a profit of 200 hp per engine. Thus we have griffons of 2250 hp per engine in the wings. Just about right to power the 120,000 lb (50,000 kg) BB-29...or the Vraciu 29.
(3) Result: a B-29 without the huge draggy radial engines. only smooth slim blisters driving pusher engines! At 30,000 feet a maximum speed of 400 mph should be possible, and on long trips overwater you could have the option of shutting down one or two of the engines to save fuel with very little drag penalty... lots of possibilities open up!!!
