Flying Vehicle Drive Unit With Adjustable Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying vehicle drive systems require additional rotary elements or separate systems for vertical and horizontal flight, limiting flexibility and efficiency.
Innovation Solution
A drive unit with at least one air channel fitted with outlet-inlet nozzles and two fans connected to corresponding engines, allowing independent regulation of air jet direction and force, enabling vertical take-off and landing without rotary drive elements or dual systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional rotary drive elements or dual drive systems are used for vertical and horizontal flight, then flight control flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by enabling a single drive system to perform both vertical and horizontal flight operations. The drive unit with adjustable nozzle directions allows the same propulsion system to generate thrust in multiple directions, eliminating the need for separate rotary drive elements or dual drive systems while maintaining full flight control flexibility
Solution Approach 2:
The patent implements dynamics through adjustable nozzle directions that can be changed during operation. The nozzles are positioned at different angles (including 45°, 90°, and 135° relative to the longitudinal axis) and can be repositioned to direct thrust vectors dynamically, allowing the vehicle to transition between vertical and horizontal flight modes using the same drive system
2Device complexity
If a single drive system is used for both vertical and horizontal flight, then device complexity is reduced, but flight control flexibility deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the propulsion system into multiple independent drive units, each with its own nozzle assembly. This allows individual nozzles to be positioned and controlled independently at different angles, enabling the single drive system to achieve complex flight maneuvers through coordinated operation of segmented propulsion elements
Solution Approach 2:
The patent adds dimensional capability by positioning nozzles at multiple angular orientations (45°, 90°, 135°) relative to the longitudinal axis. This multi-dimensional nozzle arrangement allows the single drive system to generate thrust vectors in multiple directions, effectively adding rotational and lateral control dimensions without requiring separate rotary drive systems

Function Achieved in This Case
Enables flexible control of flight directions, including ascent, descent, rotation, and horizontal movement, with stable directionality and additional rotary capabilities through independent fan regulation.
Implementation Method 1
the fan (2) with the engine (3) fixed on one end of the air channel (1), and that the other end of the air channel (1) is closed with a cover (6) having an outlet chute (7) for the draft force produced by the fan (2)
Implementation Method 2
One of the outlet-inlet nozzles openings (5) is placed in a wall of the central part of the air channel (1), between fixed fans of the drive unit, and constitutes a vertical draft force outlet-inlet nozzle opening
