Folding Canard Missile Support Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In missile launching systems, the dead space between the smaller diameter forward section of the missile and the launch canister leads to unwanted movement and flexure due to lateral shock loads, which is not adequately addressed by existing support systems, and the jettisoned collars can cause damage during launch.
Innovation Solution
A folding canard system with a hinge positioned outboard of the canard's root near its midpoint, allowing it to form an acute angle for insertion and providing lateral shock absorption and support within the launch canister, while maintaining the ability to pivot freely in flight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a ring or collar is placed around the smaller diameter section of the missile to minimize movement within the launch canister, then missile stability is improved, but upon launch the ring or collar must be jettisoned which can cause damage to personnel and/or property
Solution Approach 1:
The patent combines the support function and the shock absorption function into a single integrated canard structure. The canard serves both as a control surface and as a shock-absorbing element that eliminates the need for separate support rings or collars, thereby removing the hazard of jettisoned components while maintaining missile stability during lateral shock events
Solution Approach 2:
The canard is designed to perform multiple functions: it provides aerodynamic control during flight, supports the missile within the launch canister during handling and transport, and absorbs lateral shock loads. This multi-functionality eliminates the need for separate dedicated support components that would need to be jettisoned
2Ease of operation
If the canard is hinged near the root to allow folding for canister insertion, then ease of operation is improved, but the canard does not provide support for load while positioned in the launch canister
Solution Approach 1:
The canard hinge is positioned outboard of the root, creating a dynamic configuration where the canard can fold for canister insertion but also extend to provide load support and shock absorption during launch. The outboard hinge location allows the canard to function as a lever arm that can absorb lateral shock loads while maintaining the ability to fold for storage
3Adaptability or versatility
If the launch canister is made large enough to hold the largest diameter section of the missile, then adaptability is improved, but dead space is created between the smaller diameter forward section and the canister wall which results in unwanted movement or flexure
Solution Approach 1:
The canard serves as a self-service shock absorption mechanism that eliminates the need for additional canister modifications or internal support structures. By positioning the hinge outboard, the canard naturally extends to fill the dead space and absorb lateral shock loads, using its own structure to solve the stability problem created by the canister size accommodation

AI summary
A canard includes a first section and a second section. The first section is configured for the coupling of radial forces to a fuselage of an air vehicle, and the first section is coupled to the second section via a hinge somewhere along the radial extent of the canard. An edge of the first section near the hinge provides a load support for the air vehicle within a launch canister.
