Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
135 words
A model flight simulator comprising: 1. a model airplane having movable steering means for simulating airplane manoeuvres; 2. a horizontal transverse bearing axle defining an axis which runs approximately through the centre of gravity of the model airplane; 3. a yoke-shaped member connected to the bearing axle; 4. a wire connected to the yoke-shaped member to serve as a vertical axis for the model airplane; and 5. control means for operating the movable steering means on the model airplane from a place outside the airplane, whereby the model airplane may be suspended by means of the wire and an operator of the model flight simulator may control the orientation of the model airplane with respect to a vertical and a horizontal axis on the model airplane while the airplane is subjected to an air current.
Claim 2
Dependent Claim
