Abstract

An aircraft launch apparatus including a bottom attachment assembly configured to receive a fixed wing aircraft, the bottom attachment assembly including a saddle movable between an open position and a locked position, the saddle including one or more front engagers and one or more rear engagers configured to engage the fixed-wing aircraft, the one or more front engagers are each configured to engage a top and a bottom of a respective wing of the fixed-wing aircraft; a plurality of landing legs connected to the bottom attachment assembly; and a top attachment assembly connected to the bottom attachment assembly and configured to receive a flexible member.

First claim

The invention claimed is:

1. An aircraft launch apparatus comprising:
a bottom attachment assembly configured to receive a fixed wing aircraft, the bottom attachment assembly including a saddle movable between an open position and a locked position, the saddle including one or more front engagers and one or more rear engagers configured to engage the fixed-wing aircraft, the one or more front engagers are each configured to engage a top and a bottom of a respective wing of the fixed-wing aircraft;
a plurality of landing legs connected to the bottom attachment assembly; and
a top attachment assembly connected to the bottom attachment assembly and configured to receive a flexible member.

2. The aircraft launch apparatus of claim 1 , wherein the one or more front engagers are each configured to engage a leading edge of a respective wing of the fixed-wing aircraft.

3. The aircraft launch apparatus of claim 1 , wherein the one or more rear engagers are each configured to engage a trailing edge of a respective wing of the fixed-wing aircraft.

4. The aircraft launch apparatus of claim 1 , wherein the one or more rear engagers are forced to disengage a trailing edge of a respective wing of the fixed-wing aircraft as the one or more rear engagers move from an engaged position to a disengaged position.

5. The aircraft launch apparatus of claim 1 , wherein the one or more rear engagers are each configured to engage a trailing edge of a respective wing of the fixed-wing aircraft and are linked such that the one or more rear engagers are forced open as the one or more front engagers open.

6. The aircraft launch apparatus of claim 1 , which includes one or more vertical stabilizers.

7. The aircraft launch apparatus of claim 1 , wherein one of the plurality of landing legs is configured to also function as a vertical stabilizers.

8. The aircraft launch apparatus of claim 1 , wherein the plurality of landing legs includes four landing legs, wherein two of the four landing legs are configured to function as vertical stabilizers.

9. The aircraft launch apparatus of claim 1 , wherein the top attachment assembly includes a guard configured to engage a snag prevention member attached to the flexible member.
