Pentagon & Boeing 757 Engine Investigation: Pentagon debris matches the characteristics of a rotor disk from the Rolls-Royce RB211-535 — Too small for Global Hawk or Tomahawk

Absolutely no doubt, 9/11 has thoroughly been proven to be an inside job [many links below], the ‘New Pearl Harbor’ that PNAC perpetrated to regime-change pre-selected countries and turn America into a NSA surveillance, police state. But that doesn’t mean a 757 did not hit the Pentagon.
Some photos of the wreckage found at the Pentagon show aircraft parts consistent with a Boeing 757 or 767. Of course, these parts could have been planted after the fact as part of the coverup. But this analysis clearly shows that the rotor found was too small to be from a Global Hawk, Tomahawk missile or an APU, and was consistent with an aft compressor fan of a 757 engine.

Pentagon & Boeing 757 Engine Investigation

According to the accepted story, American Airlines Flight 77 was hijacked by five al Qaeda terrorists as it was traveling from Washington DC to Los Angeles. The aircraft involved in this hijacking was a Boeing Model 757-200 with the Boeing customer code 757-223 and the registration number N644AA. …

Those who doubt this version of events point to wreckage at the Pentagon as proof that some other kind of aircraft or missile was actually responsible for the attack. Probably the one piece of debris that has prompted the most debate is the following photo of what looks like a rotary disk from the interior of the plane’s engine. This disk could be part of a fan, a compressor, or a turbine rotor from inside the engine, but the blades are not present and were presumably knocked off in the impact.

Based on the sizes of the person standing next to the debris and other objects in the photographs that we can use for comparison, it has been estimated that the disk is approximately 25 to 30 inches (63.5 to 76.2 cm) across. Obviously, this piece is far smaller than the maximum engine diameter of 6 feet (1.8 m) or more….

However, we have already seen that rotating components within a turbofan engine can vary widely in size. … The particular engine model chosen by American Airlines for its 757 fleet was the RB211-535E4B triple-shaft turbofan manufactured in the United Kingdom. …

According to Brassey’s World Aircraft & Systems Directory and Jane’s, the fan diameter of the RB211-535E4B engine is 74.5 inches (189.2 cm). It then follows that the compressor disk hubs are approximately 27 inches (69 cm) across while the turbine disk hubs are about 25 inches (63.5 cm) in diameter. Both of these dimensions fit within the range of values estimated for the engine component pictured in the wreckage at the Pentagon. …

Two of the most common claims we have seen suggest that the plane used in the attack was a Douglas A-3 Skywarrior or a Northrop Grumman RQ-4 Global Hawk. …

This analysis indicates that all three of these engines are too small to match the engine component photographed at the Pentagon. Some sites also suggest the part might be from the aircraft’s auxiliary power unit (APU). An APU is essentially a small jet engine mounted in the tail of an aircraft that provides additional power, particularly during an emergency. However, APUs tend to be much smaller than jet engines, and the component pictured at the Pentagon is too large to match any found in an APU. It has also been suggested that the attack was conducted by a cruise missile like the Tomahawk or Storm Shadow, but these and other weapons are powered by engines no more than 15 inches (38 cm) across.…

Nonetheless, we have been able to locate the following picture of the intermediate pressure compressor section of the RB211 that appears to match several characteristics of the Pentagon debris. …

One similarity between the two photos can be seen in the cleats along the edge of the Pentagon object. These devices are called dovetail slots and provide attachment points for the compressor blades. The shapes of these slots on the Pentagon wreckage appear to match those on the RB211 assembly shown on the left. Furthermore, the “nosepiece” jutting out from the center of the disk in the Pentagon photo shares commonalities with the central shaft visible in the RB211 photo.

The above analysis indicates that the Pentagon debris does in fact match the characteristics of a rotor disk from the Rolls-Royce RB211-535. The wreckage is most likely a compressor stage given the shape of the dovetail slots. It is difficult to be certain exactly which compressor disk it is since the six rotors of the intermediate pressure section and six high pressure compressor disks are of similar size. The primary difference from one compressor to the next is the smaller span of the compressor blades as the air flows further into the engine, but these blades are no longer attached to the wreckage. However, additional clues in the photo suggest the rotor disk is probably from the high pressure section or perhaps the very last disk of the intermediate pressure compressors.

We believe the disk is most likely a high pressure compressor because of the shape of the piece jutting from its center.
