Solution Overview

Problem

Vertical landing aircraft, especially military helicopters, face risks during hung gear emergencies due to inadequate landing assistance solutions that can damage sensitive equipment and pose safety hazards, as existing makeshift solutions are not robust enough to handle the weight and protect the aircraft's underside systems.

Innovation Solution

A mobile emergency landing pad system comprising a trailer with resilient capture pads and a towable design, allowing quick deployment and cushioning of the aircraft's underside to protect sensitive equipment, is developed to facilitate safe landing in hung gear situations, featuring a trailer with wheels, adjustable connectors, and high-density foam capture pads.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If makeshift structures (tables, chairs, clothes, pillows) are assembled at the landing site to assist aircraft with hung gear, then landing assistance can be provided, but the structures can collapse under aircraft weight and cause serious consequences

Engineering Contradiction:
Improvelanding assistance capabilityVSAvoidstructural strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The landing assistance system is divided into modular components: a trailer frame, removable capture pads, and optional cover layers. This segmentation allows the system to be assembled from standardized parts that can be easily transported and deployed, while each component is designed to bear specific loads, preventing catastrophic failure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The capture pads are pre-attached to the trailer frame before deployment to the landing site. This preliminary assembly ensures that the structural components are properly positioned and secured in advance, eliminating the need for hurried on-site construction and ensuring the structure is ready to immediately support the aircraft's weight upon arrival.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If makeshift structures are assembled quickly at the landing site, then rapid deployment is achieved, but the structures may not be robust enough to handle aircraft weight

Engineering Contradiction:
Improvedeployment timeVSAvoidstructural reliability
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The trailer is designed as a universal platform that can accommodate various aircraft types and configurations. The standardized trailer frame with pre-attached capture pads serves multiple functions: providing structural support, enabling rapid deployment, and adapting to different landing scenarios. This multi-functionality ensures reliability across diverse applications without requiring complex custom assemblies.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If heavy aircraft land on makeshift structures, then landing assistance is provided, but sensitive equipment on the aircraft underside (antennas, lighting systems, infrared vision systems) can be damaged

Engineering Contradiction:
Improvelanding assistance capabilityVSAvoidequipment damage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

High-density foam capture pads are pre-attached to the trailer frame before deployment. These pads provide cushioning protection for the aircraft's sensitive underside equipment during landing. The foam material is selected to absorb impact forces while distributing the load, preventing direct contact between hard structural elements and vulnerable equipment such as antennas, lighting systems, and infrared vision systems.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The surface characteristics of the landing platform are changed by using soft, compliant foam material instead of hard surfaces. This parameter change in surface hardness and compliance reduces the harmful effects of impact on sensitive equipment while maintaining the structural integrity needed to support the aircraft's weight.

Inventive Principle:
Principle #35Parameter changes

4Ease of manufacture

If standardized manufacturing techniques are used for the mobile emergency landing pad, then production cost is reduced, but the device must still be sufficiently strong to accommodate various aircraft

Engineering Contradiction:
Improvemanufacturing costVSAvoidload-bearing capacity
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The trailer design incorporates dynamic load distribution through its frame structure and wheel configuration. The frame is engineered to flex and distribute aircraft weight across multiple contact points and support structures, allowing standardized components to handle variable loads from different aircraft types. This dynamic load management enables the use of cost-effective standardized manufacturing while maintaining sufficient strength and adaptability.

Inventive Principle:
Principle #15Dynamics

AI summary

An emergency landing pad is used to capture a vertical landing capable aircraft that has a hung gear. The device is trailer based with the trailer having a series of wheels. At least one capture pad sits atop the trailer so that a portion of the aircraft lands atop the capture pad which cushions the fuselage of the aircraft. The capture pad is made from a resilient material, such as high-density foam, a rubber or similar materials. A cover is placed over the capture pad and one or more straps cinches the capture pad and the cover to the trailer. The cover may have markings on an outer surface thereof, which markings may be light reflective. The trailer is towed to the landing site via an ordinary tug and several trailers can be chained together in series in case more than one trailer is needed for aircraft capture.
