Solution Overview

Problem

The current hub-and-spoke air transportation model is inefficient, costly, and vulnerable to security threats, with long distances, lengthy transfer times, and high operational costs, while also creating large concentrations of people that are easy targets for terrorism.

Innovation Solution

A supplemental thrust system for an airplane incorporating a submerged inlet duct, diffuser section, and turbocharger unit to increase engine power, combined with a heat exchanger for cooling, and a lightweight, efficient aircraft design capable of all-weather operation with a single pilot, allowing for non-stop transcontinental travel from any local airport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hub-and-spoke transportation model is used, then aircraft can operate from major airports with infrastructure support, but travel time and operational costs increase significantly

Engineering Contradiction:
Improveinfrastructure supportVSAvoidtravel time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The invention divides the transportation system into numerous small aircraft operating on direct routes between local airports, replacing the concentrated hub-and-spoke model. Each small aircraft operates independently on point-to-point routes, eliminating the need for connections at hub airports and significantly reducing travel time while maintaining infrastructure compatibility through use of existing small airfields.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If larger aircraft are used to increase passenger capacity, then fewer flights are needed, but the aircraft become larger targets for terrorist activity

Engineering Contradiction:
Improvepassenger capacityVSAvoidterrorist target vulnerability
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The system segments the passenger transport function across multiple small aircraft instead of concentrating passengers in large aircraft. Each small aircraft carries fewer passengers but operates in a distributed network, making individual aircraft militarily insignificant targets while collectively serving the same passenger demand through frequent direct flights.

Inventive Principle:
Principle #1Segmentation

3Power

If supplemental thrust devices are added to increase engine power, then aircraft performance and speed improve, but device complexity increases

Engineering Contradiction:
Improveengine powerVSAvoidsystem complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The supplemental thrust device is designed to perform multiple functions: it provides additional thrust during takeoff and climb, acts as a heat exchanger for cabin cooling, and serves as an air intake for the turbocharger. This multi-functionality reduces overall system complexity by combining what would otherwise be separate systems into a single integrated component.

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

Solution Approach 2:

The invention merges the supplemental thrust device with the heat exchanger and turbocharger air intake systems. By combining these functions into a single integrated structure, the overall device complexity is reduced compared to having separate systems for thrust augmentation, cooling, and air intake.

Inventive Principle:
Principle #5Merging (Combining)
