Thermal Design and Thermal Analysis of Spacecraft

  • Optimize the combination of passive and active thermal control methods to maintain all spacecraft components within their allowable temperature ranges. Passive thermal control includes tuning radiative and conductive heat transfer paths, while active thermal control includes electrical heaters. (Note: convection does not exist in the space environment.)
  • Design thermal hardware (e.g., Multi-Layer Insulation (MLI)) and its integration onto spacecraft.
  • Develop and maintain spacecraft thermal mathematical models (TMMs) consisting of conductive/radiative node networks and geometry models with assigned thermo-optical properties.
  • Predict spacecraft temperature distributions and heater power requirements using thermal analysis software and thermal mathematical models.
  • Improve the accuracy of thermal mathematical models based on thermal balance test results.
  • Coordinate thermal interfaces among spacecraft systems and subsystems.

Spacecraft Thermal Testing

  • Plan manufacturing, assembly, and verification activities for the thermal control subsystem.
  • Prepare test plans and procedures for Thermal Vacuum (TVAC) and Thermal Balance (TB) tests, and participate in testing as the responsible engineer.
  • Design and prepare thermal test setups and ground support equipment (GSE).

Development Management

  • Develop and execute plans for the thermal control subsystem.
  • Plan and manage development schedules and budgets.
  • Coordinate with thermal hardware suppliers and subcontractors.
  • Report progress and results related to thermal design/analysis, testing, and development management to Group Managers and Project Managers as appropriate.


  • Strong knowledge of conductive and radiative heat transfer.
  • Practical experience in thermal control design, thermal analysis, or thermal testing in aerospace, automotive, electronics, or robotics development.
  • Business-level proficiency in both English and Japanese.

 

  • Experience using Thermal Desktop thermal analysis software.
  • Basic knowledge of orbital mechanics.
  • Basic understanding of spacecraft systems.

    ・熱解析コードと熱数学モデルを用いた衛星温度分布及びヒータ電力の予測 
    ・熱平衡試験結果を用いた熱数学モデルの精度向上 
    ・衛星システム、及び各サブシステム間の熱インタフェース調整 

    • 衛星の熱試験 

    ・熱制御サブシステムの製造、組立および検証計画の立案 
    ・熱真空試験および熱平衡試験の試験計画書・手順書の作成。担当技術として試験に参加 
    ・熱試験の試験系および試験冶具の設計および整備 

    • 開発マネージメント 

    ・熱制御サブシステムの開発計画の策定・遂行 
    ・開発スケジュールおよびコストの計画立案・管理 
    ・熱計装部品製造業者、外注業者との折衝 
    ・熱設計解析、試験、開発マネジメントそれぞれについて、適時グループマネージャー、プロジェクトマネージャーに進捗、結果を報告する。 

    <必須条件>

    • 伝導および放射熱伝達に関する必須知識。
    • 航空宇宙、自動車、電子機器、ロボット開発における熱制御設計または解析、試験の実務経験。
