Lighter-than-Air Interceptor for Controlled Payload Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for neutralizing and capturing non-cooperative lighter-than-air (LTA) vehicles, such as spy balloons, are inefficient, costly, and pose risks to safety and security, as exemplified by the Chinese spy balloon incident, where a fighter jet and missile were used, and there is a need for a safer and more economical solution.
Innovation Solution
A lighter-than-air vehicle interceptor equipped with an airship platform, interceptor payload, and various effectors (severing, grasping, puncturing) to engage and capture the threat payload, allowing for controlled retrieval to the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fighter jet and missile are used to neutralize a spy balloon, then the balloon can be destroyed, but the cost is extremely high (up to $400,000 per missile) and the payload cannot be recovered intact
Solution Approach 1:
The invention extracts and removes the payload from the balloon envelope by severing the suspension cables, allowing the payload to be captured separately while the balloon continues floating. This enables intact recovery of the payload without destroying the entire balloon system, resolving the contradiction between neutralization effectiveness and payload recovery integrity.
Solution Approach 2:
The system segments the balloon into two separate components: the envelope (which continues floating) and the payload (which is severed and captured separately). This segmentation allows the payload to be recovered intact while the balloon is neutralized of its threat, addressing both the need for effective neutralization and intact payload recovery.
2Reliability
If a fighter jet and missile are used to shoot down the balloon, then the threat is eliminated, but the cost is extremely high
Solution Approach 1:
The invention replaces expensive missiles with a reusable airship platform that can perform multiple interception missions. The airship is a cost-effective, reusable system compared to single-use missiles, significantly reducing operational costs while maintaining threat neutralization capability through non-lethal payload separation.
Solution Approach 2:
The airship acts as an intermediary system between the threat balloon and the ground, providing a cost-effective means of neutralization. Instead of using expensive kinetic energy weapons, the airship mediates the neutralization process through mechanical cable severing, eliminating the need for costly missile expenditures.
3Reliability
If the balloon is shot down with a missile, then the balloon is destroyed, but the payload falls uncontrolled to the ground or water requiring recovery operations
Solution Approach 1:
The system performs preliminary action by attaching a capture mechanism to the airship before neutralizing the balloon. The capture mechanism is prepared in advance to receive the payload once the cables are severed, ensuring controlled descent and eliminating the need for complex post-neutralization recovery operations.
Solution Approach 2:
The payload is extracted from the balloon system and attached to the airship's capture mechanism, allowing it to be lowered controllably to the ground. This extraction prevents uncontrolled free-fall and simplifies recovery operations by providing a controlled descent path to a predetermined location.
4Loss of substance
If the balloon is allowed to continue floating without intervention, then the payload remains intact, but the security threat persists
Solution Approach 1:
The invention extracts the threat element (payload) from the balloon system by severing the suspension cables. The payload is then captured and controlled by the airship, eliminating the security threat while preserving payload integrity for subsequent analysis. The balloon envelope continues floating harmlessly without its payload.
Solution Approach 2:
The airship serves as an intermediary that separates the threat payload from the balloon envelope. By positioning itself between the balloon and the ground, the airship captures the payload and controls its descent, neutralizing the security threat while maintaining payload integrity for future analysis.

AI summary
The present invention provides a lighter-than-air (LTA) vehicle interceptor for neutralizing and/or capturing a non-cooperative LTA vehicle, such as a spy balloon. Embodiments of the interceptor may be equipped with various subsystems useful in missions to intercept, neutralize and ideally capture a threat payload attached to the non-cooperative LTA vehicle, even at stratospheric altitudes. Such subsystems may include an imaging device, severing effector, grasping effector, puncturing effector, weight-bearing apparatus, power subsystem, navigation subsystem, communication subsystem and propulsion.
