Solution Overview

Problem

Existing missile launch systems face challenges with the high impulse and temperature of propulsion jets, leading to damage and contamination of missiles and surrounding equipment, requiring heavy and cumbersome jet deflectors that need frequent repairs and complex positioning mechanisms.

Innovation Solution

A lightweight, single-use canister with a built-in jet deflection device featuring a wedge surface for partial deflection of the propulsion jet, reducing mechanical load and allowing easy adaptation for different missile types, and incorporating refractory materials for temperature resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a heavy steel plate jet deflector is used to withstand impulses and heat loads, then the missile launch function is protected, but the starting device becomes difficult to position and reposition

Engineering Contradiction:
Improvejet deflector strengthVSAvoidstarting device weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The jet deflection function is segmented from the starting device and transferred to individual containers. Each container has its own integrated jet deflection device, eliminating the need for a single heavy steel plate deflector on the starting device. This segmentation reduces the weight of the starting device while maintaining jet deflection capability through multiple smaller, distributed deflection points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container with integrated jet deflection device is designed as a disposable unit. After missile launch and jet deflection, the entire container including the jet deflection device is discarded rather than repaired and reused. This eliminates the need for heavy, durable construction and complex repair mechanisms, significantly reducing the weight of the starting device while maintaining reliable jet deflection during each use.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Object-affected harmful factors

If a heavy jet deflector is used to protect surrounding containers from heat and chemical residues, then missile launch safety is improved, but the starting device becomes cumbersome and requires complex positioning mechanisms

Engineering Contradiction:
Improveprotection from heat and chemical residuesVSAvoidpositioning mechanism complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protection function is segmented to individual containers rather than requiring a centralized heavy deflector. Each container independently handles its own jet deflection and protection, eliminating the need for complex positioning mechanisms to maneuver a large deflector between multiple containers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container is designed as a disposable unit that provides complete protection functionality for a single launch. After use, the entire container is discarded rather than repositioned or reused, eliminating the need for complex positioning and reconfiguration mechanisms.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Productivity

If a traditional jet deflector is used multiple times, then resource efficiency is improved, but regular repairs and cleaning are necessary increasing maintenance time

Engineering Contradiction:
Improvejet deflector reuseVSAvoidrepair and cleaning time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The container with integrated jet deflection device is designed for single use only. After the missile is launched and the jet deflection function is performed, the entire container is discarded rather than cleaned and repaired. This eliminates all maintenance time while the low cost of the disposable container maintains high productivity and resource efficiency.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Ease of operation

If a lightweight container with integrated jet deflection device is used, then handling and positioning are easier, but the jet deflection device must be designed for single use increasing material consumption

Engineering Contradiction:
Improvecontainer handlingVSAvoidmaterial consumption
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The jet deflection device is merged with the container as an integrated unit rather than being a separate reusable component. This allows the container to be lightweight and easy to handle while the low cost of the integrated deflection device makes single-use disposal economically acceptable, balancing ease of operation with material consumption.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The container (1) has a beam baffle (5) provided with a beam entry port (23) and beam suction (25), which are connected over a flow channel (27). A deflection device (29) is installed in the flow channel. The beam entry port is arranged on the sides of the beam baffle, and the flow channel is partially curved or bent around 10 to 30 degrees, where the deflection device is formed of a part of the wall surface of the flow channel. Wedge surface is formed on the flow channel for partially deflecting propulsion beam of a jet-powered missile (3).
