There is no off the shelf J79 that could replace the RM6C + Ebk 67 because of the separation of the engine and afterburner. This engine produced up to 12,456 lbs thrust (max military) or 17,086 lbs (max reheat). However much of this length (and a bit of the weight) is consumed by a pipe extension to connect the forward mounted engine and the aft mounted afterburner. The RM6C with Ebk 67 (as fitted to the J35D and later models) was 138” (8,140mm) long with a 44” (1,118mm) diameter and weighed in at 3,902 lbs (1,770 kg) dry (no fuel and oil in it). On the other hand US tab data includes the afterburner if the engine model was so fitted. So if you are looking at tabulated data for the Volvo RM6B or RM6C it does not include the afterburners which were the Ebk 65, 66 and 67. The Swedes did not consider the engine and the afterburner as a single unit. The comparison of tab data is not quite right. Not to derail, but a quick question: Do you know what requirement the Lansen was aimed at to compete in South Africa? Was it a strike or intercept role? Trying to figure whether it was aimed at competing against the Mirage III/Sabre/Buccaneer/Canberra, all of which were SAAF projects/purchases in the late 50's/early 60's.Īnd with the above mentioned info about the Lansen, and in context of this topic, was the J35 Draken ever offered in competition to the Mirage III to the SAAF? Whilst being aware of Palme's odd foreign policies, I wasn't aware of his mentors/predecessors relative real politik. Thanks for the info on the Swedish defence export issue. Hence my pondering wonderment at benefits. I would guess that would require a massive redesign to the aft-of-cockpit fuselage internal structure, as well as centre of gravity considerations.etc I think it has a higher airflow requirement too. The J-79 is about 2 meters longer than the RM6, about 10% wider, and almost half a ton heavier, for roughly the same thrust. I guess I was simply looking at the physical dimensions of the J-79 vs the RM6 as well as thrust. But a stall warning has to be taken extremely seriously, as the aircraft becomes aerodynamically unstable even before the stall – you have to stick to the ground rules precisely.” On the other hand the Draken withstands turbulence very well. The low-speed characteristics take some getting used to, especially in a delta-wing aircraft, as does the high angle of attack on landing. “The Draken is very responsive to all control inputs and its narrow tolerances allow little leeway, which means that pilots end up being very disciplined in the way that they fly. “That aircraft cut through the air like a hot knife through soft butter,” is how the former Draken display pilot describes the aerodynamic properties of the double-delta wing fighter. Wing Commander Doro Kowatsch, the former commander of the air surveillance wing, is today the commander of Flight Regiment 2. Following the PIO, the solution devised was to add a non-linear gearing and improve the This aircraft had high stick sensitivity combined with a linear gearing of the SAAB’s experience of the PIO phenomenon had commenced A few wind tunnel models were built with tailplanes, but during wind tunnel testing it was found that this configuration was unstable, and so the tailplane was dropped. Here was no horizontal tailplane, even though Saab engineers had considered fitting one. J35 was aerodinamically stable aircraft with some limitations. ![]()
