Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerial delivery systems lack effective control over the attitude and azimuth of payloads during extraction from aircraft, leading to unsuitable separation techniques for items with extended control surfaces and inability to simultaneously launch multiple items with directional control.
Innovation Solution
An aerial delivery system comprising a platform, linear guidance devices, and a releasable securing mechanism, which includes a method for controlling the attitude and azimuth of payloads using straps and a rotation mechanism coupled to a parachute, allowing for precise orientation and separation of payloads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If gravity extraction is used for cylindrical items, then extraction simplicity is improved, but impact concentration deteriorates due to lengthy impact path
Solution Approach 1:
A rigid or semi-rigid guidance device acts as an intermediary between the bomb bay and the cylindrical item, providing a controlled path for extraction. The guidance device maintains the item's orientation and directs it along a precise trajectory, concentrating impact on a specific target area rather than allowing scattered carpet bombing.
Solution Approach 2:
The cylindrical item is pre-positioned within the guidance device before extraction, with its longitudinal axis aligned horizontally and its rear end secured. This preliminary arrangement ensures that when extraction occurs, the item follows a predetermined path and achieves concentrated impact without requiring complex real-time control during the extraction process.
2Reliability
If multiple items are released sequentially from bomb racks, then extraction reliability is improved, but productivity deteriorates due to extended release time
Solution Approach 1:
Multiple cylindrical items are combined within a single guidance device, with each item secured in sequence along the guidance path. This merging approach allows all items to be extracted simultaneously through one extraction event, dramatically increasing productivity while maintaining reliability through the structured arrangement of items within the guidance device.
Solution Approach 2:
Multiple items are pre-loaded into the guidance device in the correct sequence and orientation before extraction. The rear ends of the items are secured to the guidance device, and their longitudinal axes are aligned horizontally. This preliminary preparation enables simultaneous extraction of multiple items without requiring repeated extraction cycles.
3Strength
If cradle separation is used for winged items like MOAB, then item integrity is improved, but directional control deteriorates due to lack of linear guidance
Solution Approach 1:
The guidance device serves as an intermediary structure that replaces the traditional cradle for winged items. It provides both the mechanical support needed to maintain item integrity during separation and the linear guidance necessary for directional control. The item is secured to the guidance device in a horizontal orientation, ensuring proper attitude during extraction while maintaining structural integrity.
4Device complexity
If items with extended control surfaces are extracted without linear guidance, then device complexity is reduced, but manufacturing precision deteriorates due to inability to control attitude and azimuth
Solution Approach 1:
The payload is pre-positioned within the guidance device with its longitudinal axis aligned horizontally and its rear end secured to the device. This preliminary arrangement ensures proper attitude (horizontal orientation) and azimuth (directional alignment) are established before extraction occurs, providing precise control without requiring complex active guidance systems during the extraction process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables controlled separation and orientation of payloads, reducing damage and allowing for simultaneous launch of multiple items with extended control surfaces, improving delivery precision and reducing the carpet-bombing effect.
Implementation Method 1
The aerial delivery system and cradle will slow significantly, due to drag created by the still attached extraction parachute
Implementation Method 2
The aerial delivery system will also pitch, with its leading edge going downward due to gravity and aerodynamic forces
Implementation Method 3
The MOAB has forward momentum due to inertia imparted by the aircraft

AI summary
An aerial delivery system is configured to allow delivery of one or more releasable items after the system is extracted from an aircraft. One or more linear guidance devices and releasable securing mechanisms allow the aerial delivery system to deploy one or more releasable items at an appropriate time. The one or more releasable items may be deployed simultaneously, or in a staged or staggered fashion. Through use of drag or lift-producing devices, the system may be recovered and reused. The attitude and/or azimuth orientation of the system may be varied prior to, during, and/or after release of a releasable item.
