“…[14][15][16][17] 2D-materialprepared films are also popular and attractive. Some examples include graphene oxide and RDX, which are used together to form a composite film; [18] hexanitrohexaazaisowurtzitane (CL-20) embedded in graphene oxide, which is used to generate a doublelayer photothermal film; [19] and the recently developed 2D material MXene (Ti 3 C 2 Tx), which is used as a photothermal conversion film by interface modification. [20,21] With regard to the mechanism of laser ignition, the photothermal-conversion effect is well acknowledged in this field.…”

Photosensitive materials, such as energetic complexes, usually have high sensitivity and cause heavy‐metal pollution, whereas others, like carbon black and dye, do not contain energy, which affects energy output and mechanical properties. In this work, donor–acceptor π‐conjugated energetic catalysts, denoted as D‐n, are designed and synthesized. Nonmetallic hybrid energetic composites are prepared by assembling the as‐synthesized catalysts into multiscale ammonium perchlorate (AP). Composites containing catalysts and APs can be successfully ignited without the involvement of metals. The new ignition mechanism is further analyzed using experimental and theoretical analyses such as UV–vis‐near‐infrared (NIR) spectra, electron‐spin resonance spectroscopy, and energy‐gap analysis. The shortest ignition delay time is 56 ms under the experimental condition of a NIR wavelength of 1064 nm and a laser power of 10 W. At the voltage of 1 kV and the electric field of 500 V mm−1, the laser‐ignition delay time of D‐2/AP hybrid composite decreases from 56 to 35 ms because D‐2 also exhibits organic semiconductor‐like properties. D‐2/AP and D‐12/AP can also be used to successfully laser ignite other common energetic materials. This study can guide the development of advanced metal‐free laser‐ignitable energetic composites to address challenges in the field of aerospace engineering.

“…Laser detonation has unparalleled advantages over conventional bridge wire detonation, such as characteristics of static-discharge proof and stray-current free, smaller size, reusability, easy-to-achieve multi-point synchronous ignition and in-line ignition, etc. [9][10][11]. In addition, it can provide technical support for research of the micro-scale detonation process and the development of new explosives.…”

Miniaturized laser-initiated pyrotechnic devices have great application prospects in aerospace and modern weapon systems due to their excellent energy output performance and reliability. In order to develop a low-energy insensitive laser detonation technology based on a two-stage charge structure, it is important to deeply analyze the motion law of a titanium flyer plate driven by the deflagration of the first-stage charge (RDX). The effects of the charge mass of RDX, flyer plate mass, and barrel length on the motion law of flyer plates were studied through a numerical simulation method based on the Powder Burn deflagration model. The consistency between the numerical simulation and the experimental results was analyzed using the paired t confidence interval estimation method. The results show that the Powder Burn deflagration model can effectively describe the motion process of the RDX deflagration-driven flyer plate with a 90% confidence level, and its velocity error is ≤6.7%. The speed of the flyer plate is proportional to the mass of the RDX charge, inversely proportional to the mass of the flyer plate, and exponentially related to its moving distance. As the moving distance of the flyer plate increases, the RDX deflagration products and air in front of the flyer plate are compressed, which inhibits the motion of the flyer plate. In the optimum state (the mass of the RDX charge is 60 mg, the mass of the flyer is 85 mg, and the length of the barrel is 3 mm), the speed of the titanium flyer reaches 583 m/s, and the peak pressure of the RDX deflagration reaches 2182 MPa. This work will provide a theoretical basis for the refined design of a new generation of miniaturized high-performance laser-initiated pyrotechnic devices.
