No, the Boeing 707 did not have propellers, it had 4 turbo fan engines, two on each wing
The ford Trimotor or Fokker F.VII
The B-52 Stratofortress has a total of 8 engines, 4 per wing, 2 per pod.
The titanic's massive wing propellers were 7meteres in diameter.
They were 23 feet 6 inches in diameter.114 inchesas big as a winmill
bigger than my pencil
A propeller is almost exactly similar to an airplane wing. A propeller has the same general shape as a wing, but it is slightly distorted to obtain maximum efficiency. Also, like a wing, many propellers change shape to perform better in different areas (eg takeoff, climb, fuel efficiency, etc.). The only two major differences are 1. the size and 2. propellers spin.
The Titanic had 3 propellers. She had 2 wing or outer propellers each with 3 blades and 23 feet in diameter, and 1 center propeller with 4 blades and 17 feet in diameter. All propellers were made of Bronze.
Two bronze triple-blade wing propellers. One bronze quadruple-blade centre propeller.
Titanic had three propellers. In the absence of solid proof, historians like Mark Chirnside feel that all three propellers had three blades. Steam engines drove her wing propellers and a steam turbine drove her central propeller. The turbine engine was not reversible although the steam engines were.
