Arrowstone Supports Aerospace Hydraulics

Introduction: The hydraulic industry is one of the crown jewels of manufacturing, with extensive applications across numerous downstream sectors, including aerospace, automotive, marine, construction machinery, and textile machinery, among others.

Aviation hydraulic components and systems, in turn, are the most dazzling gem in the crown of this industry;

I: Global Hydraulic Industry Landscape and Global Aerospace Hydraulic Industry Landscape

The World’s Five Hydraulic Giants Yes: Rexroth, Parker Hannifin, Eaton, Kawasaki Heavy Industries, and KYB;

Among them, Rexroth and KYB primarily focus on automotive components, while Kawasaki’s hydraulic products are mainly geared toward construction machinery components.
Parker and Eaton offer a broader product portfolio. Aviation hydraulic products It is the most important component of its business; together with Liebherr’s aerospace hydraulic products, it currently ranks among the world’s top three suppliers of aerospace hydraulics—a position it has maintained for roughly 25 years.
 

The following table presents the 2023 revenue figures for the aircraft and hydraulic industries.
 

As shown in the table above, Eaton, Parker, and Liebherr are the three leading players in the aerospace hydraulic market, with Eaton standing out as the clear leader.

II: Reshaping the Global Aerospace and Global Aerospace Hydraulics Industries

Introduction 1: “The world has long suffered from the emptiness of the skies,” said a veteran in the civil aviation industry.
Introduction 2: Who is China’s Eaton? Nanjing Machinery & Electrical, or... Hengli , AVIC Lihyuan, Lingfeng Hydraulics?
Keywords: machining plan, fixture, cutting tool, measurement;
 

As shown in the table above, China’s Commercial Aircraft Corporation of China (COMAC) has quietly joined the ranks of major commercial aircraft manufacturers in recent years, despite remaining relatively unknown.
Could it emerge as a “third way” and disrupt the 30-year-old duopoly between Boeing and Airbus?

For an aircraft, the fuel system is its circulatory system, the hydraulic system is its muscular system, and the air management system determines passenger comfort.
Eaton Aerospace and Parker Aerospace cover the aforementioned areas;

Liebherr Aerospace, on the other hand, excels in the aircraft landing gear sector;

Hydraulic systems are widely used in the aerospace industry due to their efficient and reliable power transmission, which enables their application in the operation of critical components such as flight control systems, landing gear, navigation systems, and aircraft engines. To ensure the stability and safety of these systems under extreme environmental conditions, hydraulic components must be manufactured with extremely high precision, placing stringent demands on machining technologies.

‘-Nanjing Electromechanical (Institute 609) As a qualified supplier of COMAC, the Nanjing Research Center for Electromechanical and Hydraulic Engineering of AVIC Jincheng has been fully involved in the type certification, joint design, and development of the C919 large aircraft’s fuel system, hydraulic system, and air management system, and serves as the lead entity for these three major systems, responsible for managing and driving domestic Tier-2 suppliers. AVIC Nanjing Electromechanical has signed multiple trilateral agreements with COMAC and Parker Hannifin, as well as with Liebherr.
‘- Hengli Hydraulics As the leading private enterprise in China’s hydraulic industry, Hengli Hydraulics posted revenue of RMB 9 billion in 2023. The company’s core product portfolio includes hydraulic cylinders, hydraulic pumps, hydraulic valves, hydraulic motors, high-precision castings, as well as pump stations and complete systems. However, Hengli Hydraulics has made relatively limited inroads in the aerospace sector; to date, its primary collaboration is with Liebherr on component integration for landing gear. Given Hengli’s current capabilities, its strength appears to lie more in individual components, while full-system integration will likely require additional time to develop.

‘-AVIC Lihyuan   The main products include Hydraulic Piston Pump/Motor for Aircraft Hydraulic Systems and Aircraft Heat Exchange Cooling System , as AVIC Heavy Machinery [600765] Its subsidiary, AVIC Lihyuan’s military-products division, lags far behind its early rivalry with Hengli Hydraulics in the construction-equipment sector, and it is a pity that it was not shortlisted as a supplier for COMAC.

– Lingfeng Hydraulics Sichuan Lingfeng Aviation Hydraulic Machinery Co., Ltd.’s main products include aircraft servo actuators, actuating cylinders, accumulators, and other flight control systems, as well as Key components of the hydraulic system are predominantly used in military aircraft, and R&D capabilities are relatively limited.
‘-North Yuci, South Shaoyang As two leading players in China’s early hydraulic industry, Yuci Hydraulics and Shaoyang Hydraulics have achieved widespread application of piston pumps/motors and vane pumps, with strong export sales. They have also made progress in construction machinery; however, they currently lack commercial opportunities in precision systems and aerospace applications, which is a regrettable situation.
