This paper proposes a functionally decoupled relay boring configuration: unarmed opening units open the channel in successive segments, and a terminal warhead unit detonates at the target depth. Each opening unit integrates five mechanisms — canted-nozzle spin propulsion, thermally weakened cutting, rationed phase-change cooling, two-stage cuttings transport and terminal self-disposal — replacing single-impact penetration with continuous cutting, and replacing the kinetic limit of a single projectile with depth accumulated segment by segment. 与 v1.0 相比,本版作出三处实质修正。第一,把工作面目标温度由 800 至 1200 摄氏度下调至 573 至 750 摄氏度,理由是该区间既能利用石英 α-β 相变(573 摄氏度,公认值)产生的微裂纹与塑性弱化降低可钻性,又不至于超过硬质合金刃口的长期许用温度;v1.0 所设定的温度窗口高于刃口材料许用温度,属设计参数自相矛盾。第二,补充一阶热与能量预算:在软化层厚 5 毫米、热效率 20% 的假设下,单位进尺软化能耗约 2.5 兆焦每米,50 米进尺累计约 126 兆焦,折合推进剂约 16 千克,仅占单枚弹上化学能总量的百分之几;而在全截面升温(等效软化层 150 毫米)假设下,所需热量约 5.05 吉焦,超过单枚弹的化学能总量,属必须规避的失效模式。第三,把全部引用回溯至原始文献页面,逐条核对年份、卷期、作者与结论原句。 Compared with v1.0, this edition makes three substantive corrections. First, the target working-face temperature is lowered from 800 to 1200 °C to 573 to 750 °C. The rationale is that this range both exploits the microcracking and plastic weakening produced by the quartz α-β transition (573 °C, a generally accepted value) to reduce drillability, and remains below the long-term service temperature of cemented-carbide cutting edges; the window set in v1.0 exceeded that service temperature and was therefore internally inconsistent. Second, a first-order thermal and energy budget is added. With a softened-layer thickness of 5 mm and a thermal efficiency of 20%, softening energy per unit advance is about 2.5 MJ/m, or about 126 MJ over the 50 m of one segment, equivalent to roughly 16 kg of propellant and only a few percent of the onboard chemical energy. Under full-section heating (equivalent softened layer of 150 mm) the requirement rises to about 5.05 GJ, exceeding the entire chemical energy of one unit, and constitutes a failure mode that must be avoided. Third, every citation was traced back to the original publication page, with year, volume, issue, authorship and the wording of conclusions checked item by item. 预算分析给出一个比 v1.0 更准确的判断:制约本构型的不是能量总量,而是热量的空间定位精度与传输效率。能量预算本身相当宽松,但一旦热量无法约束在工作面毫米级薄层,需求将以软化层厚度线性放大并迅速击穿能量上限。 The budget yields a more accurate judgement than v1.0: what constrains the configuration is not the total energy but the spatial localisation accuracy and transport efficiency of heat. The energy budget itself is generous, yet once heat can no longer be confined to a millimetre-scale layer at the working face, demand scales linearly with the softened-layer thickness and rapidly breaches the energy ceiling. 本文未检索到与该构型同构型的公开方案,也未发现违反已知物理定律的障碍;但温度窗口的稳态维持、盲孔排渣流道、多段同轴保持与热迹制导四项约束仍属未验证环节,文中逐项标注了其证据状态。构型与逐段累加的深度关系见图 1,温度窗口的收紧与单段单元的热流分区见图 2,三条加热路径的能量开销对比见图 3。 No public scheme of the same architecture has been found in this review, and no obstacle violating known physical law has been identified. Four strongly coupled constraints nevertheless remain unverified: steady maintenance of the temperature window, the cuttings path in a blind hole, multi-segment coaxiality, and thermal-trail guidance; their evidence status is annotated item by item in the text. Figure 1 shows the configuration and the depth accumulated segment by segment, Figure 2 the narrowing of the temperature window together with the heat and flow zoning of a single unit, and Figure 3 the energy cost of the three heating paths. 关键词:深地目标打击;热辅助破岩;接力掘进;相变热管理;气固两相输运 Keywords: deep-buried target strike; thermally assisted rock breakage; relay boring; phase-change thermal management; gas-solid two-phase transport
