Are there any aircraft with a 4-wheel nose landing gear and a 16-wheel main landing gear? I need this to answer my review of an aircraft design project.
4 main bogies with 4 wheels each, nose gear with 4 wheels.
this one has a better view of the wheels, but it's a CGI:
4-wheel nose gear is rare, 16-wheel mains are more common: Boeing 747 (4 trucks with 4 wheels each in 2x2 config), Avro Vulcan (main trucks with 2 axles with 4 wheels each), HP Victor (same as Vulcan), Shorts Belfast (same as Vulcan).
The Antonov AN-225 is also close to being configured this way. It has 4 nose wheels but has 32 mains.
The large Antonovs use two two-wheel bogies for their nose gear, whereas the C-5 uses one four-wheel bogey. For the mains, the Antonovs have multiple inline two-wheel bogies, whereas the C-5 has four six-wheel bogies. As Moo commented while I was writing this, those distinctive six-wheel bogies can be deceptive from some angles and give the appearance of 16 main wheels.
