3D Printable Landing Gear - Nose Gear Version 1
Work has begun on the 3D printable nose landing gear for the L-1011 RC Airliner
Initial Fitting and Kinematic Modeling
About the Design
I have designed the nose landing gear in a way that allows it to be fully assembled independently from the fuselage frame. Once assembled it will slide into the gear well as one component and then secured in place with either 3mm screws or, for a permanent installment, 3mm pins/wooden dowels.
For added strength the landing gear has steel reinforcement embedded within the 3D printed parts, mainly the strut and trunnion, to ensure a stiffer more shock resistant part. Various materials will be tested to ensure durability, easy of printing, and resistance to heat.
Testing will be done using the following 3D Printing materials:
Nylon
Carbon Fiber Filled Nylon
Polypropylene
Glass Filled Polypropylene
Carbon Fiber Filled Polypropylene
Nose Landing Assembly

Kinematics
Kinematic Motion Study of the Nose Landing Gear for the RC 1:20th Scale L-1011-500 Airliner. In this video the articulation and gear bay door sequence it tested for proper obstruction free movement.
These two images show an early version of the design where the kinematics for the landing gear were determined to ensure clearances and proper placement of the trunnion and tire clearances.
