Nose cone
Disclosed here are systems for detachable airframe components including detachable nose cones, propeller assemblies and motors. In some example embodiments, the assemblies include a nose cone with a connection receiver, a motor assembly with a rotatable section, where the rotatable section includes torque arms configured to secure with the nose cone connection receiver, and a propeller assembly, configured to connect to the nose cone.
1. An assembly, comprising:
a unitary cover;
a motor assembly with a rotatable section configured for rotation about an axis of rotation, the rotatable section including torque arms configured for insertion into openings formed in a sidewall of the unitary cover such that the openings extend transversely in relation to the axis of rotation; and
a propeller assembly extending through the unitary cover.
2. The assembly of claim 1 , wherein the motor assembly is detachably coupled to an airframe.
3. The assembly of claim 1 , wherein the openings in the unitary cover includes at least two openings, each with a snap ledge.
4. The assembly of claim 3 , wherein the torque arms each include a snap flange configured to mate with the snap ledges.
5. The assembly of claim 1 , wherein the propeller assembly includes a propeller connector bar supported between the torque arms and extending through the unitary cover such that rotation of the rotatable section causes corresponding rotation of the propeller connector bar.
6. The assembly of claim 4 , wherein the torque arms are deflectably resilient toward each other to allow the nose cone to snap on and off the torque arms of the motor assembly.
7. The assembly of claim 5 , wherein the propeller connector bar extends through slots in the unitary cover.
8. The assembly of claim 7 , wherein the unitary cover includes two openings and two slots.
9. The assembly of claim 7 , wherein the propeller connector bar includes a center hole and the motor assembly includes a center post, the center hole configured to fit around the motor assembly center post.
10. An assembly, comprising:
a unitary cover with a first pair of openings defining a first axis extending in a first direction and a second pair of openings defining a second axis extending in a second direction transverse in relation to the first direction;
a motor assembly rotatable about an axis of rotation, the motor assembly including with at least two rotatable torque arms each with a tab configured for receipt within the first pair of openings in the unitary cover to thereby connect the motor assembly to the unitary cover;
a propeller assembly extending through the unitary cover and rotatably supported by the motor assembly.
11. The assembly of claim 10 , wherein the propeller assembly extends through the second pair of openings in the unitary cover such that the propeller assembly extends transverse in relation to the axis of rotation, and wherein the second pair of openings in the unitary cover are configured as slots such that the propeller assembly is slidably insertable through the unitary cover.
12. The assembly of claim 11 , wherein the propeller assembly further includes at least two propeller blades that are configured to attach by at least two hinges.
13. The assembly of claim 10 , wherein the motor assembly further comprises a center post configured to fit in a center hole of the propeller connector.
14. The assembly of claim 10 , wherein the unitary cover is filled with plastic foam.
15. The assembly of claim 10 , wherein the at least two rotatable torque arms of the motor assembly each include a snap flange and are deflectable.
16. The assembly of claim 15 , wherein the at least two rotatable torque arms of the motor assembly snap flanges are configured to snap into the unitary cover at least two tab openings by a snap ledge on each nose cone at least two openings.
17. The assembly of claim 10 , wherein the motor assembly is detachably coupleable to an aerial vehicle.
18. An aerial vehicle rotor assembly, comprising:
a unitary cover including radial openings extending into the unitary cover;
a motor assembly including connection arms configured for engagement with the radial openings to connect the motor assembly to the unitary cover; and
a propeller assembly extending through the unitary cover.
19. The airplane nose assembly of claim 18 , wherein the motor assembly is detachably coupled to the aerial vehicle.
20. The airplane nose assembly of claim 18 , wherein the connection arms on the motor assembly are deflectably resilient.
